WOOHOO!! Body Language training (fi-na-ly)!
Just to keep it short an non-time consuming.
I work as a dancer and performer (which explains my enthusiasm, and occasionally I get blessed to give (artistic) instructions for other stage performers (mostly singers), and I give courses to dance teachers, to become better leaders and give more effective classes.
Now in my experience with giving various artistic classes at various school (often as part of their school curriculum), I noticed a kind of degradation in behavior and culture customs among teenagers and young kids. This includes bullying, selfish (empathy-less) behavior, exclusion, etc. which has many origins, and many horrible consequences, sometimes permanent damage....
I plan to offer/give sort of "interactive seminar" for various children and young adults, to adres these topics and hopefully (at least) make them aware of it at a young age, to become aware of their behavior, where it might come from, and what effect it has on others (and what effect they would want to have on others).
This has more to do with sociology and psychology, though I don't think it is far off body language. And body language can not only be a part of it, but perhaps be a separate course by itself. (I'm sure I can develop a children-friendly version is I have the right/enough knowledge).
So to come back to the main questions asked:
This is the type of stuff I would like to know more about for the sake of understanding and educating children and young adults (mostly), about (anti-)bullying, empathy, self-analysis, and care, for yourself and others.
All other information (for business for example) is either way useful for other job offers and things, but in my heart less needed for society and...world, i guess.
lots-o-love, thanks, and encouragements to all who took the time to read this.
