well, no matter how cliche it is, there is some truth in it.
my dear, you can not gamble on something hesitating and being afraid of losing. if situation forces you to make the bet, result solely depending on where the ball would fall on the roulette bowl, then so be it. have the courage to place the ante and hope for the best.

the result is not going to change if you hassle the croupier. the result is not going to change if you hesitate. and the result is not going to change even if you bet slowly.
at the end, you would either win or lose. and if situation forces you to place the bet, what is a better choice than to place it somewhere where the bet history favors you?
my love, do it with no regrets or pull out.
