Today I was really tired.  I had an early morning class.  I thought all morning that I would just come home and take a nap until my night class.  Instead, i pushed myself to get on the treadmill.  It felt really good when I was on the treadmill and felt really good when I got off.  I was proud of myself for this small victory.  Even though I was tired, I pushed myself to exercise and it felt great!
