What do you think about the idea that teenagers need more guidance from adults and a stricter environment in which to grow up?

The teenagers have confusing behaviour and are moody during this period. On one hand, they feel disappointed and desperate because of all problems they need to face as they grow older. On the other hand, they are very agressive and boisterous reacting to everything concerning their family or school.
I firmly believe that rebellious adolescents need some advice and guidance from their parents. So they should live in a loving family environment in which they will feel safety and freedom. As far as parents are concerned, they might not be massively strict, but patient and permissive setting boundaries to teenagers' behaviour.
