Yeah, and we should take advantage of that "sometimes", maybe we can experience winning streak in some games or win big in slot machines. Then we should quit while we are in the top. But the problem is that when greed sets in, then that will be the time that we are going to lose.
We thought that we're invincible and win every games in black jack and or roulette, but when the luck change then that is going to be the worst feeling as we might regret and think that we should have exited already when we have the winnings. Now we are fighting for just our capital to come back and worst it will really be that we can't get and win it as well.
I can't even remember how many similar situations and moments I've had. There's a big win, I should leave with it. But no... Greed gets the better of me and I'm sitting in front of the slots again, increasing the bet. The result, as I suppose, is known to you - empty pockets and a sea of disappointments. Well, why did I continue to play? It was never enough.
