I started school in the medical field, got married side tracked into accounting and from accounting to office manager to executive assistant.  No this wasn't my first choice and if you had asked me high school if I was going to be a "secretary" I would have denied it loudly.  My mother retired as a book keeper for a state bar association and I did not want to have to do anything close to what she did!  I even managed to flunk typing II in high school in protest!  
I've been an ea for the last ten years and LOVE my current position and I really can't imagine doing anything else at this point even after spending 2005 getting my paralegal certificate. No day is ever the same, my job stays at the office, and my bosses are great.  I don't want the stress of a commission salary, the month end year end number crunches from accounting or the hr stress of managing anyone else's time.  For me it may not have been the position I thought I would be in 20 years ago, but it fits me now.  I think any job is what you make of it, as my brother often says "the world needs ditch diggers too!"
