Pain is GOOD?

Well the last 2 days I haven't been walking quite right. . . my calves are really sore! Apparently I am not in as good as shape as I thought :) However this will not stop me, it just makes me want to do it again, and again until the day my legs don't hurt anymore! Then I will push them again til they hurt again. No Pain, No Gain right? I will get miles of walking done this weekend as we are going to Universal Studios. I may be busy and will not post for a few days~ Hope everyone has a good weekend! I am sure I will. . . . even if my legs hurt, I will push past the pain and have fun!
