A limit written before the match outlives the tilt.
Discipline is less about willpower and more about defaults: amounts, time, and an exit rule that does not depend on how you feel mid-session.
Fix a figure you can lose
Choose an amount that changes nothing else if it disappears — not rent, not savings, not credit. Write it down as a hard ceiling.
Split it into sessions
Divide the ceiling across sessions in advance. A per-session cap prevents one bad night from consuming the whole month.
Time-box the screen
Set an alarm before you start. Fatigue and long sessions correlate with larger, faster stakes and worse decisions.
Agree a stop rule
Decide both an upside exit and a downside exit. Hitting either one ends the session — win or lose, no renegotiation.
Review weekly, not nightly
Nightly reviewing magnifies noise and invites chasing. A weekly total shows the trend that actually matters.
Use the operator's own tools
Licensed operators generally offer deposit limits, loss limits, session reminders, time-outs and self-exclusion. These are more reliable than self-restraint because they are enforced by the system rather than by you at 2am.
Keep a plain record
One line per session — date, stake, result, mood — turns a vague sense of "roughly even" into a fact you can read. Most people are surprised by their own numbers, and the surprise is more useful than any pick.
