1. Bet on sports that you are good at, don't bet on sports you are bad at.
2. Bankroll management. You should only be betting 1% to 10% of your total bankroll.
3. Never bet on heavily juiced lines. Like a line at -1000 for example.
4. Never bet on heavily valued lines. Like a terrible team at 100 to 1 odds to win championship.
5. Teams with home field advantage tend to win games, especially in football.
6. Be a strategic gambler by picking your spots and wait for the right opportunity. Never be an impulsive gambler by betting for the action or just because it's your favorite team.
7. Stay emotionless all the time. Bet like a robot. There's no place for emotions in this profession.
