Jobs, Jobs, Jobs

I was thinking recently about all the jobs I've had over the years. What do these actually qualify me to do in the real world? Have I found any sort of expertise in holding down these jobs? Am I a better (or worse) person for these experiences? I love to make lists so here is another that is interesting to me.

All the jobs I've had to this point in my life:

babysitter (in high school I did this Monday through Friday year round - during the school year from 3:30 to 6pm and in the summer from 7am to 8pm)
piano teacher
paid and unpaid church nursery worker
retail store associate, cashier, and customer service rep
waitress
bartender
on-air DJ & production for a crappy little FM station
Avon Lady
undergrad research assistant
graduate assistant
college adjunct instructor
housekeeper/personal chef
temp (administrative)
promotional sales rep
promotional sales coordinator/buyer
manager of consumer research
marketing research analyst
Creative Memories consultant
office manager
field supervisor
greeting card display merchandiser
content management specialist

And the most important jobs I've had (and make no mistake, sometimes they can be real work), wife and mother. Mostly I feel like I've been a Jack of All Trades and Master of None. I wonder what my next opportunity will hold for me.
