Everyone should treat themselves.
I just treated myself to a facial. I'm not usually big on the putting-of-stuff on my face, but wooo, I needed it, and it was great. Part of the facial is a neck, shoulder, and arm massage, and that was wonderful.
Why the self-treat? Because I got paid this week! It was very nice to see the boost in my earnings on the new job. The first two paychecks were scrambly-scrambly with different additions and subtractions, but this was the first one that's "standard"; i.e. all my deductions for retirement, health insurance, and parking were taken. So this is how much I will get paid each month, and it is a little more than my mental calculation was coming up with, so that is very nice.
Of course, I figured out where the extra is coming from. I used to get paid every two weeks. This meant that twice a year I had an "extra" paycheck in a month. Since I'm now paid once a month, it's as if two whole paychecks are split into 12 pieces and I get one piece each month. That adds up to just about the extra amount over what I was estimating.
