Most casual bettors lose not because they pick bad games, but because of bet sizing. Here's a quick framework to fix it:

1. Set a unit size, not a flat bet.

A 'unit' should be 1-3% of your total bankroll. If your bankroll is $500, one unit is $5-$15. Never bet more than 3-5 units on a single parlay, no matter how confident you feel.

2. Fewer legs = better math.

A 3-leg parlay at -110 each has roughly a 30% chance of hitting even if each leg is a true coinflip. A 6-leg parlay drops that to about 8%. If you love parlays, keep them to 2-3 legs and treat 5+ leg parlays as lottery tickets, not strategy.

3. Correlate your legs on purpose.

Instead of parlaying 3 unrelated games, parlay outcomes that move together — e.g., a team favored to win big + that same team's star player to score over X points. If your read on the game is right, correlated legs hit together far more often than random ones.

4. Track every bet.

Most bettors think they're profitable and aren't, because they never log results. Spend 30 seconds after each bet writing down the line, the stake, and the result. After a month you'll know your real win rate — no more guessing.

Small discipline changes like this move you from 'fun bettor' to 'sharp bettor' faster than any single pick ever will. Good luck out there. 🏈🏀⚾
