Here's a graph I made representing how long I've been in grad school vs. how frequently i think about how much i might like to have some other sort of job.
I've been thinking of a new one every hour.
butcher? baker? candlestick maker?
record producer? I'm good at being the man.
secretary? I can type pretty fast. Detail oriented! (Sometimes)
Nature guide! I totally went hiking one time! I could probably figure out how to put up a tent, no problem. Fishing? meh, i can learn!
Farmer - I may kill all my plants, but that's probably because i'm so preoccupied.
and so on...
