The First 30 Seconds of Working Out

When I first start working out, I feel great. I feel on top of the world, untouchable. I feel like I can run for miles and miles, not stopping for anything! The endorphins are flowing, and life is good. All my bad thoughts about exercising go away, all of the negative feelings built up from the last time working out just disappear.

Then, there's 30 seconds later...

But then the next day I feel freaking awesome and unstoppable, so I do it over and over again. Oh yeah.
