I started off in computer programming before having a major career switch. When all of the computer jobs started going overseas years back I seen the light at the end of that tunnel. While I was making more money as a programmer (although not that much more, honestly), service jobs can't be shipped to China or India. I do miss that work a little, though I may not have a job now had I stayed. That job market is sketchy to say the least. The more complicated vehicles get the more security this profession has.
I used to be able to type 130wpm. I am down to around 60 now. I spend more time thinking than typing. It doesn't flow like it used to.
