Budget, budget, budget, budget, budget, budget, BUDGET!!!
True intelligence makes best use of time, energy, resources. You don't need Big Macs. You don't need the nicest shoes. You don't need the Luxury addition car. What you do need is good money allocation towards commodities, or what-have-you, that have the best chance to multiply your wealth and, therefore, free up some of your future time to focus on the next things on the priority list.
