You have to consider the fact that pretty much our entire personality becomes what it is during our adolescence. That’s pretty much the most important phase of our lives. I would say an adolescent who is completely normal and rarely, if ever, shows any signs of a personality disorder is one adolescent I would be more worried about.

Both comments are correct. Adolescence is a time of rapid change and normal ups and downs. However, serious signs of anxiety, hopelessness, depression, or changes in functioning should be checked out.

The schooling system needs to be changed and teachers should be selected on strictness and given more powers to punish bad behaviour.

Any deviants need to be dealt with right away before it grows out of hand.

School is for education and training, not for socialization. People need to accept this fact. When you go to a school you sign a contract that says you will be fined and kicked out if you do not behave yourself in an acceptable manner.

If you don’t perform well it means 1 very simple thing: you’re not working hard enough. If other people can do something, why can’t you? You simply just haven’t put in the effort. And that’s something only you yourself can remedy, through hard work.

If you rebel you get kicked out. That way the students who want to study can do so in peace without being influenced by the disruptive troublemakers.
