Never give in to peer pressure. Drinking your youth away is a waste of time, trust me I know. Youre still young so you need to make up your own mind about life etc. That will determine the kind of person you will become. But sounds like you already got a good head on your shoulders, good on you mate.

Take advice from the guys on this site, they have a lot of great advice to give, ive been given loads already.

I wish I knew the stuff you do when I was your age, would have saved me a hell of a lot of money, time, friends etc...

To be honest it already seems as though youre already on the right path, learn from the guys on this site and do parth and just even take some time to reflect on things and the teachings that the Gurus gave us. Things will become clear, I promise.
