@Ionus,
i usually change jobs about every 10 years, i get bored and look for something different
out of highschool, i worked in a retail environment (picture framing) loved the job, love art and design stuff, loved the people we dealt with (lots of artists)
next i moved to start up manufacturing job, worked setting up production lines, moved to producing silicone rubber (pretty cool machine like a giant pasta maker, used to blend silicone, curing agents and dyes)for use in the plant, and eventually moved into the quality assurance department
last working in a 10 acre greenhouse, managing the packing line, assisting the grower, light maintenance
now trying to find what will probably be my final career, not easy in this market, but i'll figure out something
