Bankroll management is the least exciting aspect of sports betting and also the most important. You can be the sharpest handicapper alive, but without proper bankroll discipline, variance will eventually destroy you. I learned this lesson the hard way through painful early mistakes that cost me months of profits in single bad weeks.

The Unit System

I bet in units rather than dollar amounts, with one unit representing 1% of my total bankroll. This system automatically adjusts bet sizes as my bankroll grows or shrinks, preventing the death spiral of chasing losses with oversized bets. Standard bets are 1-2 units, with 3-unit plays reserved for highest-confidence spots occurring maybe twice weekly.

Never Chase Losses

The biggest bankroll killer is increasing bet size after losses trying to get even quickly. This emotional betting leads to catastrophic losing streaks. When I'm down, I maintain or even reduce bet sizing, trusting my process will win long-term. Some weeks you lose - accept it and move on without panic.

Separate Bankroll from Life Money

My betting bankroll is completely separate from money I need for rent, food, or bills. It's entertainment/investment capital I can afford to lose without affecting my life. This psychological separation prevents desperate betting when the bankroll is down. Never bet money you need for living expenses.

Track Everything

I maintain a detailed spreadsheet logging every bet - date, game, bet type, stake, odds, result. This data reveals patterns in my betting: which types of bets are profitable, which times of season I perform best, where I'm leaking money. Without rigorous tracking, improvement is impossible. You can't fix what you don't measure.
