Boundaries
Set the boundary before the account exists.
Limits are more useful before emotion, match pressure, or losses enter the picture. Decide what you can afford to lose, how long you will spend, and when you will stop.
Money limit
Only consider discretionary funds. Never use rent, bills, savings, loans, or money owed to someone else.
Time limit
Match schedules can stretch attention. Decide your session length before you start.
Loss limit
Do not chase losses. A loss limit only works if you stop when you reach it.
