I made my first buck when I think I was about 7 years old - which would be around 1959. The family was short on money and we were making "potholders" out of those old nylon yarn loops on a metal frames. My brothers and sisters chose all the sedate colors, all that was left was shocking pink and turquoise. So I made my potholders out of that. For some reason I set off trying to sell them door to door, and a local diner bought one and gave me a dollar for it. I had no idea what that meant, but as soon as I got home I was relieved of that dollar with a pat on the head and instructions to made more and go back to the diner. Needless to say the waitress didn't buy another one but I suppose the dollar helped buy some food for that week at home. Later on I figured that the color combination sold the pot holder, although to tell the truth the things didn't insulate against heat all that well, and of course they melted if they got too close to a flame, lol.
After we moved out west I had some not very successful paper routes,and then an after school job at the variety store at Cole and Carl in SF. I remember being fascinated by all the various sundries stored in the basement. I think that job paid 10 cents an hour, not really sure of that. The old eastern european couple that owned the place shut it down in the mid-60's and that was that for a while. In my last year in high school I got a more steady job doing janitorial work for the Post Office. Weird place; I used to feel so sorry for the mail sorters, it looked like such deadly boring work. I imagine they felt sorry for me pushing a broom. I grew to hate the smell of the old cheap coffee left in cups in the trash cans, combined with the ever present grit that every post office seemed to generate. I got to keep the money from that job, and it helped get me through the first year in college. The work study jobs in college were a lot more interesting - ranging from testing grapes in the viticulture department (where I got a taste for fresh zinfandel grapes) to measuring the transmittance of various materials to "soft x-rays" for a group that was studying the first black hole discovered (Cygnus X-1), to trying to grow banana trees from tiny slices of their cores. In a sense I don't count my first "real" job until I graduated from college and got a full time job working in a university lab doing medical research. But compared to the others it was kind of boring, lol.
