Glutton For Punishment vs. Workaholic

Neither title sounds very complimentary, but I've decided that one or the other of them probably applies to me. I have a full time job that I really enjoy. It comes with a regular daytime, no weekends or evenings schedule, it's challenging and I have great guys to work with. But you know, there's always that drive to make a little more $$ and hopefully afford a house, a trip to Europe, and a trip to Hawaii this year. So, enter the Second Job. I am a pro at this lifestyle. For the space of about 5 years I was dually employed (yes, I'll admit that it's hard for me to sit still for any length of time). For part of those years I was still only working about 40 hours a week and the other part of that time I was working an insane 55-65 hours a week. This time around I decided that I would like to work in a retail pharmacy so that I could experience that side of the business. I also decided that I could only handle an additional 12 hours a week. So far the new boss has had a bit of a problem understanding the 12 hour limit, but I think we're finally talking the same language. And a nice thing about the whole deal is that I really like the job. I had missed working with the public (although I didn't realize it until I was behind a cash register again). So far a lot of what I do is count pills, unpack shipments, and a little customer service. I think the worst part is going to be learning all the in's and out's of insurance. Yuck.
We'll see how it goes!
