    Blockchain technology (How decentralized, automated networks are already changing the future of mankind)

    Translated by Google. Click to view original.
    Blockchain technology is a short term with an enormous depth of meaning. Decentralized, censorship and manipulation-resistant and tamper-proof networks are the future of many everyday processes and that already today, even if most of them may not be aware of it.

    Using the example of Bitcoin, this course is intended to illustrate why blockchain has enormous disruptive potential for many important fields of application in everyday life and why it will no longer be a part of our lives in the future. In terms of content, it should be explained on a logical and predominantly non-technical level how the security of a blockchain network is created, maintained and why manipulation is not possible here - which explains the use and importance of this technology.

    About Me

    Welcome!
    My Name is Marc, I am 26 years old and conduct my tour of duty in the German Army. I am actively conducting several sports since I am 15. Sports and an active Lifestyle are my life, therefore I like to share my knowledge and experience with others.

    My personal experiences expand to the following sports:
    • Aethletics / track
    • Road racing (bycicle),
    • Climbing/Bouldering,
    • Weightlifting,
    • Intervall-Training (HIIT)
    • health sports
    • Corporate Health Management

    Education

    Abitur (highschool) in Nordrhein-Westfalia, Masters Degree - specialization Conflict Psychology - in Social Science, Licensed Trainer, Track trainer, Corporate Health Managament-Coordinator

    Experience / Qualifications

    • 4 years as Track Trainer at TSV1860 München
    • Corporate Health Management Coordinator of Luitpold barracks in Dillingen a.d. Donau
    • Personal Trainer with > 10years of personal experience in sports
    I am a sports officer in the German Armed Forces, I trained athletics youth at TSV1860 Munich for 4 years and am a coordinator for company health management as well as a licensed trainer. That's why I offer a wide range. From simple • "Sport to get into a beach figure" about • functional training, • weight training, • Most performance-oriented training, right down to • Health sports. What we go through as a topic depends only on you.
    Everyone of us - unfortunately - gets into conflict situations now an then. Especially in those situations it would be extremely beneficial to all affected parties to understand each other, whereby this is the most unlikely occurrence then. Those conflicts pretty often tend to stir up and cause nothing than harm and suffer to all affected parties. This course intends to convey an alternative, more empathetic perspective, which is fundamentally based on scientifical evidence derived from Social, Cognitive and Behavioral Psychology. Equipped with this new knowledge the participant gets enabled to take a more sophisticated and sustainable position in conflicts. A perspective that should not only enhance the ability to reflect his/her own conflict-related behavior, but even more to understand the regarding behavior of other persons. Ultimately understanding the emotional behavior of him/herself and others can prepare to prospectively contribute in a constructive instead of destructive manner in case of conflicts.

    ✅DEEPEN YOUR INTIMATE SELF-KNOWLEDGE, YOUR SEXUAL DESIRES & OVERCOME YOUR BLOCKAGES
    ► Learn to know your intimate and sexual desires, deepen them, assume them and perceive their meaning, while being aware of your own limits and those of your partner, understand your blockages in order to overcome them, take advantage of the approach socio-cognitive of sexual desire, better integrate the functioning of one's partner, integrate tools / techniques / methods / know-how / key phrases to take pleasure while leaving it to spontaneity & naturalness, improve the link between affectivity and sexual intimacy but also communication with your partner, play (...): these are examples of the objectives of these personalized sessions, in order to ultimately improve your intimate and sexual satisfaction, accompanied by a mediator specialized. ➤ Together, step by step, it's about getting to know each other better (through your past experience, what you like or appreciate the least about yourself / about the other), by analyzing situations in a thorough and pragmatic way. Indeed, this step is essential in order not to orient towards / "tackle" a pre-established model, but to adapt to each situation. ➤ In parallel, from the first session, once the key points are better understood / assimilated, and the objectives gradually defined, tackle, based on your daily life / your experience, the art of sexuality and its subtleties, while valuing the complexity of sexuality and not its complications. ► My mission: to help you understand, analyze, discover and discover yourself to better enjoy yourself, while gaining self-confidence & acting in order to no longer be limited by your beliefs. ➤ If the discretion and confidentiality of the coach are essential, it is therefore a question of offering a tailor-made program / training, following an initial 'diagnosis'. ► These sessions can, for example, deal with how to regain confidence and make you reconnect with a complex but not complicated, subtle but not tangled sexuality, in short fulfilled while understanding the key elements of your own psychology and that of your partner (... ). But also how to strengthen your sexual charisma to unlock your potential and take pleasure. ➤ Objective here again: to introduce concrete techniques / methods which make it possible to communicate easily, in a fluid, efficient and always natural way, while mastering situations. ➤ Non-verbal language, sexualization and avoidance of the friend zone (...): the objective being to demystify these themes in theory and in practice. ➤ Coaching is based on precise questioning techniques, helping the person being supported to find a solution to a problem. At the end of each session, the coachee will master new ways of thinking, actions to accomplish and will have better motivation. Depending on the clients' expectations, the coach can suggest other approaches. ➤ So what do the first individual coaching sessions look like? First, a first exploratory contact during which your expectations are examined, the nature of the request and the context are evaluated, a 'diagnosis' is discussed, taking into account your difficulties, your needs, your objective. Then, it is a question of developing a precise procedure and proposing lines of work. A relationship of trust is gradually established through a benevolent alchemy, where listening, empathy and the absence of judgment are central. ➤ Thus, after having carried out together an initial assessment of the situation, a kind of inventory, it is a question of determining the objectives to be reached, the feelings and the questions related to the situation as well as proposing actions to achieve your goal, resolve constraining situations that stand in your way, using tools that will be offered to you according to your situation to get out of your comfort zone and change your perspective. ➤ The guide then asks questions aimed at exploring solutions aimed at achieving the objective, through experiments and exercises. Through various tools (drawing, role playing, metaphor, visualization, etc.), this questioning helps to change perspective, get out of an impasse in order to explore various options that you might not have thought of. this way, based on tools and experience. For example, it could be a new way of thinking about difficulties or another approach to identifying and considering resolving conflicts or a progression in terms of personal development or in terms of a career focusing always on the development of personal resources and self-knowledge. At the start of the next meeting, the coachee begins with a summary of the activations and the evolution of the state from the last meeting. This step makes it possible to have an evaluation of the positive points and those which are less so in order to readjust the set strategy. ➤ Concretely, ONE SESSION = SOLUTIONS / proposals / concrete suggestions to put into practice for the next session in order to overcome blockages or improve self-knowledge. Note that during the videoconference session, all the notes are transcribed in the chat so that you can access them at any time when you wish.

Anxiety is a mental and physical malaise, born from the feeling of the imminence of a danger, characterized by a diffuse fear which can go as far as panic. While anxiety is a one-time emotion & often occurs as a fit, whereas anxiety can be more chronic in nature.
