It reminds me of something from Robert Kiyosaki's book "Rich dad, poor dad" (I'm surprised I'd quote that) that basically says that the things you need to do or pay will be done or paid, while the ones that not necessarily will be done or paid might not. Therefore do the unnecessary ones first because the necessary ones will be done anyways. This way you end up with e.g. both leisure time and work done instead of just work done but no leisure time. An interesting thought, in my opinion.
