As a gambler, we must be able to stand firm and control our emotions either the situation is a win/win or lose/lose.

Why ? After winning, if you get too excitedm you will rush into stakes, and get rekt back to square one.
If you lose a stake, and got upset and desperate to recover your stakes, you could get further rekt which is definitely unhealthy.

Peradventure you always rush into gambles and got lucky and won, retrace your steps so you can steer clear of avoidable losses.
