Of what i see and what i face now, i've come to conclude that adolescence is quite a difficult period in one's life. You don't know what to do exactly, and you are anxious how things may come about, all the while hoping that your dreams come true to some extent at least. At the end of which you'd have lost that hope and wish for any good sign fervently.
You are always thinking of a kinda brighter tomorrow, which is totally invisible. And you think of 'life' so as to say and how its treating you and all that. Maybe turn a little philosophical if that could bring some solace (i'm not sure).
