What is the most difficult problem for a young person when he leaves shool?

The most difficult problem for a young person when he/she leaves school would be forming an independent person out of yourself and finding a sense of self-worth in this life. Growing up under parental control without being used to carrying responsibility for his/her own's actions can be quite challenging, especially at the times when all the stakes are upon you. Besides, the after graduation time is exactly the one when you have to realize what you want to do in your life and the concrete steps needed for that, which requires a lot of dedication and strength.
