Have you ever had a"How did I get here/What am I doing" moment?

Oh...I have had many of these moments usually followed by me saying.." this is what I wanted to do!!! This is supposed to be enjoyable!!! Oh ya real cool....I pick this for a f@#$ing hobby!!!" Those are the real bad moments. Then I hunker down and, gut through whatever it was that caused this and marvel at the finished part. I have also said this when I sell a car I really should be keeping....but....there always seems to another one on the way.
