Fuck it, dude. Do what feels right to you. Not that insomniasexx and _refugee_ aren't giving you objectively good advice, but there's nothing like learning on your own how to act successfully and unsuccessfully. You can read a whole manual on how to fly a plane, but in the end, you need the hours in the cockpit, if you catch my drift.
Agreed - my sister is 20 going on 21 and she wants to talk about her relationship problems all the time. And I sit, and try to listen, because that's what she wants me to do, and not tell her what to do, because the fact of the matter is that even though my advice might be right, or save her from heartbreak or assholes or whatever, she is not going to do anything sensical until she learns that everything she's trying right now doesn't work first hand. So go on and do whatever you want and make mistakes - I think people have to in order to learn lessons - but damn if I'm not going to be like "Dude, seriously? Seriously? I told you this - unhelpful as it may be! - a few months down the road.
