I've always enjoyed my job, or if I didn't I started looking REALLY hard for a new one!
My first job was delivering newspapers, and from the time I could walk, I wanted to do that, because all my older brothers were doing it. My very feminine Mom used to say, "She wants to be a paperboy when she grows up!!!"

When Dad found out we could get college scholarships from the newspaper company, he said, "Let her." So I delivered the afternoon paper for four years. It felt like having a "beat" because I made the same rounds every day, saw the same people, and picked up all the news and noticed things. Perfect for a future writer. (and I got the scholarship, one of only two girls that had gotten one.)
During college I was a Pizza Hut waitress, because you could eat your mistakes, and you took home money EVERY NIGHT! And you got instant feedback -- if your attitude was good, you got PAID for it.

I learned that being nice to people and helping them have a good time was a rewarding skill.
Then, I pursued my passion and faced my greatest fear: writing something that everyone would read. I had my first newspaper articles published in my hometown paper when I was 20. Because our Feature Writing professor said we HAD to have something published somewhere or we'd flunk the course.
The elderly man I wrote about planted all the azaleas in our hometown, which now has a Flowertown Festival coincidentally this weekend that draws 60,000 plus people. Sooo this was 30 years ago this weekend my articles were published. He got sick and went into the hospital and they put my articles on the wall over his bed. I found my calling!
During college, I fulfilled my third-grade dream to be a teacher by taking a couse in which I taught French to third-graders one semester.
I realized ADULTHOOD IS FOR FULFILLING YOUR CHILDHOOD DREAMS.
After graduation, I went to work for the same newspaper company that gave me the scholarship (not a requirement, just a coincidence.)
After that I have been a publications director for a Medical University, radio station promotions director and announcer, head of community relations for a medical center, Chamber of Commerce vice president of community development, Medical center magazine editor... redefining myself each time my husband's promotions moved us to a new community. He stayed in the newspaper business, so I just stayed in it vicariously.
The only time I really hated going to work, I loved the job, but I couldn't stand the boss or the people I worked with. Thankfully, that was very rare, and it didn't last more than one year. I looked and found something better as soon as possible!
Now, I am on the verge of launching my own business, a marketing and public relations service.
This has been an interesting thread to read how people got into what they do and what they like about it!
