I think one of the best jobs I ever had was my first: Paper Delivery Boy -- it taught me marketing, sales, delivery, and of course collections (and sometimes lack there of). It taught me fiscal responsibility and a thing or two about "showing up" -- rain or snow, I delivered newspapers everyday because that was my job.
It taught me to plan ahead to not only have enough money to cover my costs, but also to save money for the future: my very first computer, a refurbished Apple ][+ was purchased for the princely sum of $830 my then life savings after delivering newspapers for nearly seven years.
That computer was an investment for me -- I sold my first piece of software, a custom registration system for the local municipal summer program a year later.
One of my all-time favorite books is George S. Clason's "The Richest Man in Babylon" -- a should-be-required reading for all pre-teens in my humble opinion. One of the characters suggests that "work was his best friend" -- in my case it was the love of learning and the pursuit of the highest and best education I could obtain in order to be the most effective person I could in whatever work came my way.
I've found that, time and time again, in all the positions I've had the privilege to serve, that the ones I loved the most did not feel like work. In fact for the very best positions I've joked with my management that "I'd almost pay you to let me do this job"
I think the thing I learn from every experience is actually more about human nature; the good, the bad, and the ugly.
I have been continuously employed since I was in fourth grade. The longest position I held was the one I created for myself. You don't have to be an entrepreneur to find satisfaction in your work, you can create new positions for yourself where you are.
Today's Big Idea: "Write the job description for the one you want, not the job you have."
When you think about all the job experiences you've had, which one bubbles up as your favorite and why?
