No offense GTC as I don't think you're a dummy but I disagree with you here. A play either has +EV or it does not, there is no inbetween. The whole bit about making too many plays is wrong and misguided, usually it's directed to a player that is on the wrong side of things in the first place. Limited plays equates to limited success to an advantage player, it's that simple. Limited plays to a player that is not going to win only means he will lose slower, selective betting does not turn a loser into a winner.
In short? If you participate in something that has a negative expected value you will go broke eventually. The determining factors are how often you play, how big you bet and how long you will live. If you live long enough you will indeed go broke with a stagnant bankroll. If you are on the right side of things than there is no such things as too many plays. That's equivalent to a casino trying to limit rolls on a crap table, there's no need for that when you are getting the best of something.
Making too many plays is usually confused with someone that's just on the wrong side of things and doesn't know what he's doing. Making too many bets is not what most people's problem is although it might make you go broke slower, the real culpit is not knowing what you're doing. That's what sends you to the poorhouse, not making too many plays.
