Of course, players often have to fight the temptation to put everything at stake, especially if the winnings come gradually and in small amounts. But often "all-in" is unjustified - just because it feels like it. To go "all-in", you need more than just a desire - you need at least inner confidence
Short but precise, you need to have that confidence if you take that kind of bet, win it all or go home empty handed, just need that convincing courage to take as you see opportunities not just becuase of aggressiveness which mostly leads you to take that kind of a call and regret after.
Most of the time, when you call this one and you win, instead of quitting you push for another thinking that luck may be there for you and allow you make more money.
