Getting older

I can't believe how bad I felt exercising today. I felt like I had no power. The worst part is that I was overweight by at 148. That's not any worse than usual, but I've been cutting back somewhat, and I just felt so bad today... Now I'm faced with a serious choice. What do I give up? 1)Birthday Cake 2)My goal weight at 145. There really is no other choice. I worked out every day last week. The next sacrifice is changing my diet. Doing what I am now is not getting me where I need to be... And thus the real sick part of getting older begins.
