discipline is born from a behavior, from your daily activity.
you cannot become a discipline player when you have a bad behavior ( indiscipline in your daily life )
i agree with discipline you have gambling in smart way as it will avoid you from greedy , in the end you can get profit.
I've learned that in a hard way. I lost all my earnings. I had profit from playing smartly and found a strategy that looks promising. Probably, it's like stumbling in gold. When I tripled my bankroll, I thought, it won't hurt to get a dollar more or so. I lost everything. It's true that you will lose in the long run, no matter what your strategy is. Or maybe i'm just unlucky
everyone will surely call their losing everytime as just unlucky day or so.
but the truth is more than just a luck only few people can have that 'luck' to win and walk away with a lot of money .
why? a gambling site built for making profit , they have a house edge and it will always make you looks fool.
