Long ago, I divorced myself from the big win dream, and play freerolls or play money poker for the sport. Don't take that literally, I still expect a big win somewhere along the line. This whole post may not tell well the stress I was relieved of with that divorce.
When I hit a bigger win like up to $15 bucks (WHoo Hoooo), if I don't have a specific CC event in mind, I will party with that money. The party will be the biggest buy in it will buy. It has not happened yet where I parley that freeroll into a 3rd stage, but when it does, and if it is significant, then I will start thinking about that money. Otherwise it wasn't mine to start with, and won't be mine in the end. It only represents another stack in another game.
But truly, I play the cheap games for the sport, with hope only of having a good game against reasonably good competition.
All that said, your plan is better than no plan for those who still are actively working toward that big money dream.
