Finally felt like "running"

I only ran for 600m this evening, but for the first time I actually felt like I was running.  It felt great!

I had my mind set on going 1/2 mile, but I ate track, o-well.

Its been difficult to not push myself really hard, I felt guilty leaving the track after only doing that much.  I've always battled in my head, not wanting to cop out and quit before it gets really hard - and in the past I've almost always won that battle and pushed really hard.  So on one hand It feels like I'm giving in and not working hard -- but I want to enjoy running & I want to enjoy the rest of my evenings with the family, sans headache.
