Hey Roman,
very nice of you to share your experience, even it was quite emotional I can see(just what we try to avoid in trading) :)
It is great that you put down your mistakes, this way you will have them in mind for a longer time, and just make sure not to repeat any.
No worries, most of the pieces of advice I give in the courses are from mistakes I have done in the past. :) But I did not repeat any of them, so make sure you do it too.
Anyway, ones again, great of you sharing this, I am sure it will be useful to many beginner traders here!
