Adolescence is a hard period of life not only for parents but for teenagers as well. You can find a lot of (inform) and articles for parents. They offer different solutions on how to deal with problem children, how to talk to teenagers and how to make them listen to what they are told to. Still, have you seen much advice given to teens? Although young people won't probably like to listen to any of them at this age, we still want to present three (help) tips to those who are help facing troubles of this hard period of life. Try not to react too (aggressive) when someone (including us and this article) gives you any advice on your (behave) future life. Try to analyse everything and think whether they are really useful for you.

When you can't find a common language with your parents, try to put yourself in their shoes and find a compromise.

If you feel any physiological or (psychology) changes that bother you, tell your parents about them. In most cases, there are simple (explain) to the processes that happen with your body and mind at this time.
