Managing resources is key. Personally I use the triad Time-Money-Attention, but I think I like yours better. Attention presumes the requisite mood or motivation.

Time, money, and mood seems to me like the three most important limited resources we have. The next natural step is to apply cognitive tools from economics on each of them. The etymological origin of the word is basically "allocation of limited resources" after all. I've found this to be immensely useful.
