If you dont have discipline then most likely you will fail.
Discipline has no link to gambling.
you don't gamble with discipline. That would mean you intend to have a strategy and to win.
You can't have a strategy. it's useless.
Gambling is for the fun of it! For the thrills and how you wish to hit that button again
You can discipline yourself mentally to only gamble with a certain amount of money per week.
Gambling is fine as long as you set yourself limits.
The dicipline i am refering to is the controll you have for yourself that if its time to go home, you should go home and not push through. Just like that things. Sorry but i am sick of hearing those "gambling is for fun" because if you lose already 10BTC in that fun, then you should call doctor to cure you being an addict.
