Some days (actually LOTS of days) I'm pretty hard on myself. I ran 18 miles today, but I'm still beating myself up about it because it was really hot by 9:30 and I walked way more than I should have. It's very easy to forget how far I've come, I think more so for me than anyone.

It's important, every once in a while, to look back at the path and see how far you've come. Just as important as looking forward toward how far you have yet to go.
