Free advice take it or leave it
A few days ago I completed my one year work anniversary(is that how it's said) at my first job. And this rant is basically stuff I learnt and stuff I wish someone had told me when I was starting out. Here goes:-

When you are starting out your first job you would be a fresh out of college and people around you in college are your friends where as people around you at work are colleagues. Your friends can like you, but you have to earn the respect of colleagues.

If you sit yo ass too long u will become fat(started going to the gym again).

Don't bother your seniors too much. they have their own shit to deal with.

Don't bring your personal shit to office I don't want to hear how cute your dog looked while it took a dump on your carpet.

Avoid the person who gossips.
It's a two way street.

Whatever you find amazing your boss may not you know coz you are a geek and your boss isn't.

Don't talk to people when they are coding.Yeah just don't.

Avoid "below the belt" humor you may look funny but you loose respect in the long run.

Keep upgrading yourself don't stop learning.

Admit stuff you don't know don't Bullshit.

To sum it up it's a game of respect, respect of knowledge,respect of skill and most of all respect of attitude.
