Yes.

These days I make more money than I spend, so if nothing exceptional happens, I may be able to create such safety net for myself in a few months. But before really using it, I want to be sure that I will use it well, not waste it. And by "being sure" I mean doing something that would convince a rational observer. Any by convincing a rational observer I mean... what you said.

If I can do something cool during weekends, and if I can do it not just randomly, but according to a plan, only then there is a chance that I will be able to follow the plan after the safety net opens.

My future self is the same lazy guy as my present self. If my present self can't follow the plan, I don't trust my future self. May the BeeMinder help me...
