We don't have to continue gambling if we already wins and remember to cash out the wins money before our minds changes. We can enjoy the win money when we can withdraw and forgets to playing gambling for a while.
We can come back to casino anytime we want so there is no rush to come back to the casino. But yes, if we place a bet for the last game, that will give us more tension because we hope that the last bet will give the win.
It's difficult being in that situation where you will either regret that you didn't cash out or you will celebrate with a lot of money in your wallet. For those brave enough to continue, keep it up. But for those who badly need the money, cash it out as fast as possible and just live with the last results. There's actually a way to avoid regret. Don't look at your parlay slip for maybe 2 days or a week, and then just check it after you have enjoyed the money that came from cashing out early.
