1. Betting too much
Bankroll management = 1% of your roll per typical bet. New bettors typically bet 5-10% (or more). Drop your stake size by 10× and watch your discipline improve.
2. Chasing losses
The math hates you for this. After a loss, your next bet should be smaller, not bigger. Period.
3. Parlaying everything
Parlays look fun. They're priced with massive commissions. Most should be avoided unless you're betting independent +EV singles.
4. Not line shopping
Same line at three books often varies by 5-10 cents. Always shop. Line shopping guide.
5. Treating boosts as free money
Boosts are usually on markets the book WANTS you to bet — meaning they're still -EV after the boost. Run the math.
6. Ignoring the close
Your record can lie. Your CLV cannot. CLV explained.
7. Betting tilted
Walk away after losses. Always. Tilt costs more money than bad picks ever will.
8. Not tracking
If you don't track, you can't improve. Track every bet from day one. After 100 bets you'll know more about your own betting than 95% of bettors.
FAQ
Is sports betting hard to learn?
The mechanics are simple. The discipline is hard. Most beginners take a year of disciplined volume before becoming consistently +EV.
How much money do I need to start?
$50-$200 is enough to start. The number matters less than your discipline. 1% per bet means a $100 roll bets $1 per game.
