When I did bet on football, and it was not a high dollar amounts by any means, I had one rule that I stuck with no matter what.
I never Bet on my Team. Cowboys in the NFL of course and WVU in college.
I learned that no matter what I tried I would always lose betting on or against either team.
So no matter what I would not bet on them.
Funny thing was my Father in law would ask me what I thought of a WVU or Cowboys game and I would give my opinion on what to bet...If he followed my advice he would win that bet UNLESS I would bet along with him lol.
So quit betting on those two teams.
Won some, lost more but never lost enough to hurt by any means.
Same if we would go out and play poker machines.
If I got a good amount of credits I would cash them out. After that I would put however much money I wanted to keep (always what I brought there at the very least so at worst I would go home even) in my back pocket and not touch that money.
Even if the wife would ask If I had any left to gamble I would give her some from my regular amount but never from the back pocket.
At the end of the night I would go home (if I had won enough to put in back pocket) with what I came in with.
I had seen too many times where She and/or her parents would rack up huge credit amounts only to turn around and put it right back into the machine and walk away with nothing....even if they cashed out they would eventually put it right back into the machine for the most part.
