Know The Game: Some games do give you better odds than others. There is a wealth of information both on the Internet and in print to inform you of the odds you face in any given game and the strategies that will help shave the house edge to a minimum. Spend a little time reading and you'll spend a lot less time wondering what happened to your money.
Know The Budget: Let's say you've got $1,000 and you expect to gamble five times a week for the next two weeks. Then your budget is $100 per session. If you are unfortunate and you spend your budget, then walk away. Enjoy the rest of the day knowing you kept your budget and prepare to win the next day. Do not touch any other day's portion of the budget.
Keep Emotion Out Of The Game: If you find yourself betting your rent money, your next car payment or if you have lost the last twenty bets in a row - stand up and walk away. You cannot possibly think rationally and you cannot keep your emotions from influencing your decisions. You must play the odds not play your emotions.
Don't Play While Under The Influence: If you are stoned, drunk, or half asleep, you are a lesser player than you are straight.
Fun is The Name Of The Game : Unless you're a professional player with a proven track record, you're playing for the pleasure of it. For 98% of players casino gambling and sports betting is recreation -- you're spending money to be entertained.
