like life lessons, or whatever
don't be the guy who gets drunk. drink sensibly and you'll be the man. there is nothing more tiresome than a pissed up prick. be the guy who is still drinking rum quietly at 4am, while all others are swaying wildly.
lick a lot of pussy - if all else fails, this is your get out of jail card. enjoy the experience - basically, don't be a selfish cunt. in my experience, you can fall down on other aspects of a relationship if you're more than happy to go down on your partner A LOT. and look like you're enjoying it, ffs.
that's all I have
