...but first you've got to THROW IT

Your willpower, or intent, is like a boomerang. Project it the wrong way, and you will waste time and energy. Project it the right way, it will come back to you and you will have a gain in results for a net zero in expenditure. If you're losing energy, feeling run down or wasted, you should ask yourself whether you have any "open-ended" commitments, things that drag on forever with no clear way to end the cycle and get your boomerang back. Then, figure out how to put an end to them properly.
