BRM is all about limits and boundaries. You want to limit your exposure to losses; to the detriment of making huge gains. The story is consistent:" I played free low entry tournaments, won some money and blew it at the heads-up cash games." If your goal is to win enough to comfortable play heads-up cash games, it's a lofty goal you may attain, with some extreme luck.
The only bad thing is that a lot of your opponents in the tourneys and at the cash games are good, not as many fish, like in big tourneys,
You can forgo patience if you have limits you are comfortable with. It's great to win dollars, but the kick should be in the win, not the dollar amount. "The play's the thing", as the saying goes.
