After going through a lot of problems of different levels of complexity of acceptance, I realized several important and at the same time simple and complex things:
1. You need to be able to find something good even in the most terrible. It's like the light catcher from Harry Potter that was given to Ron Weasley
2. You need to be able to accept what cannot be changed in any way. And the sooner - the better, but also more difficult, of course.
3. You need to find interesting areas of knowledge in which you don't know anything, but having understood them, you will be able to make your life and the lives of your loved ones better
4. You should always sincerely help your colleagues and loved ones, because this help will in any case be reflected in your direction
5. The longer and more you depend on installations based on receiving only fast hormones of joy, the more difficult it will be in the future to realize the dependence of your difficulties in life on this and correct this situation.
Peace to all!
