Why am I working when I'm jobless?

Today I woke up early to finish up the ad project for my previous company. I was feeling frustrated because the mistakes in that document were just so overwhelming. My ex-manager called me and told me not to bother with fixing everything wrong on it. Otherwise, the boss would think I spent too much time and tried to rip him off. I was offended by that comment. The main reason I left that job was because I couldn't get a raise for the last 3 years working there. He was too cheap! And even now I'm not charging them my fair rate. I was a little upset, but I knew I shouldn't take it personally. I mean, you can't argue with boss's cheapness. So I hurried up and finished the project. By 10:30 I was emailing and uploading the file to their site. It wasn't the most pleasant morning, but at least I got stuff done.

I ate and relaxed some more. When I was preparing to go to the gym, suddenly I felt super sleepy. So I went to take a nap. I love having naps. I woke up an hour and a half later, hit the gym, and came back to eat an early dinner. Then I did some shopping at TJ's and watched some TV. Mom called to ask me to bring a bunch of stuff to her. All bulky food items. I was hoping to travel with a light luggage, not anymore. Whatever. We'll see how things go.
