It looks foolish to me to gamble my profit when I win. But it's true, that's one of the traits of a real gambler, they tend to gamble everything including the last cents that they have in their pocket and then restart again with their life by rebuilding and earning money and then later on they will just repeat it again. No changes, that's what you will see with a gambler, it is their usual routine.
I have experience winning good amount with parlay previously but now, I lose my winnings and that feels like I am just wasting my time. But who am I to complain, I do this with my own will, so I need to accept this. I can only stop losing when I stop gambling.
" You never count your money When you're sittin' at the table There'll be time enough for countin' When the dealin's done "
That simply means, don't get too excited, you will be upset when you end up losing.
