Aside from paper routes and mowing lawns/shoveling snow for a neighbor, I got my first job as a Tea-Leaf Reader at 16: really.
There's a story behind it that I'll share briefly. When I started driving I was expected to pay for gas, which is not unreasonable at all. But my mother, who expected this, consistently undermined my efforts to find employment by not giving me phone messages for days or refusing to others because she didn't want me out "too late", so after about three months of this, I took the subway into Boston and went to a Tea Room (as they were called) downtown across from the Common downtown.
The owner didn't quite know what to make of me when I applied, so she had me do a reading for her which genuinely impressed her and I started that afternoon. I worked between three and four days after school and all day Saturday. On a good day I could make anything from $50 up (sometimes much more).
My mother was livid, but for whatever reason didn't forbid me from doing it. I worked there for two years :wink:
