Your Betting Rules

Just wondering what individual rules each other place on themselves when it comes to having a bet. Obviously they will be different for most people depending on the seriousness you take your punting.
Serious and the not so serious answers welcome. Ill get the ball started
1. Only ever bet if i can afford to loose.
2. Only ever bet on something i will get to watch or get live score updates.
3. NEVER EVER EVER EVER bet on the Redbacks to win.
4. Never ever tell the wife if i have had a win.
5. Never bet on a cricket match played between two sub-continent teams
6. I never back a horse first up from a spell
7. And i will never again back against a 30+ game winning streak like i did with the Ire vs NZ union game on the weekend.
This type thread may have been done before if it has i apologise.
