That's if you have the luck to double the money on that day, and how are you sure you will not lose the money back the next day with this plan? Frankly, I can only sense two things in this attitude, they are fear and over-expectation. The two are bad in gambling as fear will only make you do what you do not want to do and when you should act, you might cowardly prevent it because of it. This is why you believe you can run home as quickly as possible after doubling your money. And for the over-expectation, is equally bad because no one can certainly predict what could become of betting, it may only raise your emotion if it doesn't happen as you planned it. This calls for a neutral mind whenever we gamble and we must have viable plans before engaging in it.
