Set a Fixed PHP Budget
Decide the maximum amount in Philippine pesos you will spend before you start. Write it down if that helps. Once the budget is gone, close the session. A ₱500 entertainment limit is ₱500 — not ₱500 plus whatever comes next.
Treat the 65bmw session the same way you would a cinema ticket or a night out. The money is for entertainment. Whether you finish ahead or behind, the planned amount should be the ceiling, not the starting point of a chase.
