The Rules of Eve.
1. Do the tutorial. All of it. At least once.
2. Don't mix guns. Go long or short range but don't mix.
3. Don't mix tanks. Armor or shields but not both.
4. Don't mix passive/active tanking.
5. Don't shoot blues.
6. Don't smack talk.
7. Don't use autopilot, in low sec or 0.0 especially.
8. Never forget this is a game not a job.
9. Don't rush into a bigger ship without the support skills.
10. Don't undock in anything you can't afford to loose.
11. Learn to control the distance between you and your target. Close or far, if he's where you want him then you win.
12. Thinking outside the box is good. Fitting against your ships bonuses never good.
