Jordi Nomen, a Philosophy professor for 30 years, has written 'How to talk to a teenager and make him listen to you' Nomen: "Although it's hard to believe, for them the most important thing is family and then friends". "I speak of self-determination because they advance towards their maturity, their autonomy, to decide for themselves and to become stronger in the face of life," he says.

"If we don't let them be teenagers and continue treating them like children, we overprotect them and hurt them"
