It doesn't matter if you want to or not

I keep telling my self that.... It doesn't matter if you want to do something... you need to reason that if it's healthy for you (i.e. exercise) or going to make you a better person (i.e. going to your kid's classroom), then you should make it happen regardless of whether it is something you want to do. Motivation is fleeting and I need to get over the MOJO requirement of my diet/exercise/life plan. I need to just DO IT which is SO cliche. In the long run, I know that I will feel better all around. I KNOW THIS...
