Why -> Must

There's a big difference between "I would like...", or even "I should..." and "I must."

...Namely, I tend not to be motivated enough to do the things I would simply like to do, or things I probably should do. Sometimes, but not always.

But when I come up with reasons that I must do something... it gets done. These are things for which avoiding the consequences and reaping the rewards far outweigh the pain of getting them done.

I must brush my teeth. I must pay the bills. I must earn enough money. I must have a Flying Star eclair.

Point being, when you really want to accomplish some goal, make it a must.
