Ok, a good example of this - I hit a " personal best" this morning, I ran 5K in about 27 minutes. A year ago, I couldn't walk 5K without being winded and exhausted. Then, this was part of my fitness class, we did a mixed cardio/weight circuit for another 30 minutes, and I did it all. All with a bad cold.

I'm so proud of myself. If I told my sister that, she would have some nasty comment and roll her eyes. Which is sad.
