Observation #8 (I didn't count 7 but its there)

OK. After reading Smart Women Finish Rich, I decided I wanted to be smart and I wanted to be rich. I've put myself on a strict weekly cash budget to make sure I don't overspend. What I would like to know...

why is it there are always HIDDEN expenses people have and no HIDDEN INCOME?

Case in point--I had a dance class, a haircut, and a chiropractic appointment for this week. I also knew I would be renting a car for 2 weeks while mine gets fixed. So far this week, the--homeopathic doctor said, "OH! This credit you paid for doesn't cover the visit. So that's $25."
--chiropractor said, "OH! You're in bad shape. Come in again this week for another $20."
--body shop said, "OH! The insurance company only just approved your claim. So it's going to be another two weeks.

So that's an extra $45 on my weekly budget and another $120 from my savings, which will again put me $200 more this month that I intended to spend, like EVERY month for the past year (I didn't know natural health was supposed to stress you out from the financial burden it puts upon you). So now I have these HIDDEN expenses, is my boss going to walk in and say, "OH! Look at that extra work you did on our database. That's an extra $45." Where's the HIDDEN income?
