I have more responsibilities than ever now that I have a career in hand and I can't manage to maintain my brother.

We were really close when we were growing up like any other siblings, but now that I have so many priorities I am barely home and I can't help him throughout his day to day life and I feel as if he has gotten himself in trouble.

He smokes weed with his friends and is being a total f boy by messing around with girls. I feel like his school is more important and he has a lot of potential but he's not concentrating because he would rather spend his time doing this shit. I can't tell him other wise because he's a ruthless teenager that will bring up my own past and say I'm not the one to judge.

I have no idea what to do. I feel like talking really doesn't get through to him. What the hell should I do!?
