In the back of my mind, I do have plans but I'm not making specific things that I will do with my winnings even if the game has not yet been planned, I don't want to be disappointed it's like counting chicken when they are still eggs it's very premature, you have to focus first on the game if you're in luck and if you win then you can plan what you want to do with your earnings.
It is a great feeling and you can plan well what to do with your winning if the money is already in your hands.
Of course because even if we badly do, how can we do it when there is no physical cash yet in our hands? It's because it's already deposited in the casino and we are currently planning if what games we will choose and play. If it's not deposited yet, the money can still be smaller than to what we are planning to achieved.
Planning in advance is still beneficial because we might end up spending the money on something that we don't genuinely like and we will only regret it later on. It only depends on the plan though. The ones that is story tell in the OP is an example of plans that we must not do. We also need to know and accept that shit happens.
