1. Don't bet more then you can afford to lose, Golden rule.
2. Majority of your bets should be straight/single wagers. Parlays are sucker bets but sometimes 2-Game parlays can be very handy but don't go for 5-Game, 10-Game Crazy parlays.
3. Stay emotionless all the time. Bet like a robot. There's no place for emotions in this profession.
4. Patience & Discipline is the key. Develop these skills.
5. Money management is extremely important. Use a money management system and stick with it religiously.
6. There should not be dramatical difference between your stakes. Don't place 2 unit on Game-A, 10 Unit on Game-B and 40 Unit then Game-C.
7. Be selective. Pick your spots and wait for the right opportunity.
8. Always shop for the best line, Always! So you should have an account in multiple books.
9. Set goals, write down your goals. Realize your target in your head first.
10. Always check THA DIESEL's thread before placing a bet. His Jinx is too strong. Final rule is probably the most important one
