Writers Block

I have been having some trouble writing lately. I read a lot of health and fitness blogs, and some of these writers are amazing. They make me feel like I can get up and go and run a marathon and eat healthy and lose weight... and right now I don't feel like I can write like that. I have a bunch of post ideas winging through my brain, and little notes on them so I don't forget what I want to write about, but I don't feel inspiring enough to write some of them. I gotta find my mojo.
