Luck or experience?
nobody really totally succeeds in gambling, the losses are bigger than winning, you can succeed for years if you can take care of your gambling habit, you stopped when you are having a bad day and you are losing a lot, and you can manage your winnings too by not to continuing anymore when running out of luck.
I think it is about an individual deliberation in order to succeed, by making sensible strategy and self-control to avoid attaching aggresive reactions on gambling. Unfortunately, when luck has running out of our way will lead us to failure. And somehow, experiencing failure will enhance our knowledge to create viable and sensible strategy that may used to defeat loses. It is just logical cycle in order to achieve thrive and being wise is preferably good aspect to deal consequence.
