I took the same route. Wise!
   I went to a guidance counsellor at 23. My friend wanted to start
   a record label with me performing my piano stuff in churches. I
   liked to improvise/play (still do) and was willing to go along
   with it.

   But that guidance counseller gave great advice: I was deciding
   between computer programming/computer engineering and music. She
   said, "You have to decide what is your VOCATION and what is your
   ADVOCATION".

   I could've done either. Then I looked up the pay scales. [I had
   other choices too - psychologist, minister, teacher,
   occupational therapist]... and computer work was WAAAAAAAY
   higher than the rest... _and_ didn't require a diploma.
   In the end, I've become everything I ever wanted to become. What
   I do to make money doesn't have to have to SEEM to do with my
   true callings in life, and I can pursue them anytime. You can
   express yourself THROUGH any job that gets you money.

   I think that's why so many INFPs are waiters / waitresses. We
   can care for individuals and their needs on a daily basis, serve
   many people, make them happy.

   But doing computer work, I could serve and care for people just
   as well.
