Here is some good advice

Dont work alot. Specifically, dont work at a job with a low salary that requires you to work like 60+ hours a week. Its just insane. I work around 50 and it sucks. More importantly, don't worry about work too much. So what if you mess up, it can be fixed. Rarely is something not fixable. And if you work for a large corporation they can absorb the damages as if it was nothing.
Just work at something you really love. You've heard it a million times, but save yourself the heartache and the headache and just head down that road now instead of later. I think thats most peoples mistake is that they know that they need to do what they love, but they procrastinate and put it off till later and they wake up 30 years later with a lousy pension and hardly any savings and can do nothing more then sit home all day and watch Bob Barker and Oprah, cause they never developed any passions, hobbies, and didnt plan to have any money to do what they really want or any plan at all to do it. That isnt going to be me.
