Yeah, I've been a vampire most of my life. I still find myself up most nights.
I liked freelancing, which is similar to self employment, but without the book keeping end. Just picking who you work for makes a big difference in quality of life. Most I ever made annually working a real job was about 47000 & pretty good benies. Temper lost that job (and a really good friend) after four years.
My first freelancing job was for a tech temp firm and paid, 27.50 hourly, time and a half for over 40 hours a week or eight hours a day, double time for weekends and triple time for holidays. first contract lasted about a month. The company that contracted me was very, very behind on a 3D anime/video tradeshow thingy using touchscreen and lights controlled by the computer. They provided a place to sleep, meals, things to keep me awake and worked me14 hours or more a day with one day off each week to go and look at my house and show my pets I wasn't dead.
The money *sigh*
I knew a free lance aircraft mech a few years ago. He made two other brothers and myself canes out of Aircraft aluminum alloy. Fast in your hand, as light as solid wooden cane, pretty much unbendable or breakable. He was kind and the cane goes everywhere with me.
