Type on the computer a lot... redo things over and over. Correct things that were broken when originally programmed. Or people go to the doctor or dentist and are turned away.
I get paid largely while posting on Resetera (don't we all, though?). That, and pretend to do stuff on computer intermittently so it sounds like I'm busy and can't be bothered.
People come to my co workers with the shape of their caves. They are shown an indoor forest of examples of synthetic indoor grass and they choose what grass they like. I am told. I take my equipment and enter the forest alone and harvest the grass they like in the shape of their caves. Men come. Take the grass. The world continues to spin. Monthly I am rewarded for a good harvest.
