Good enough for who it's for, I always say, working for myself..
Well not always!
When I was young I worked on a maintenance crew. We were digging a ditch down to a leaking steam line -- it was hot summer work and clay stuck to the shovels from the steam. Miserable work down in that ditch. Afternoon, boss pulled up in his green air conditioned pickup truck, rolled down his window a bit and said, "How you men doing with that ditch?"
An old Vermont farmer I was working with looked up and said, "Gainin." and went back to work. We all laughed and kept shoveling, too. Stupid question. Boss drove away. That one word became a habit with us on that crew. It would answer almost any question.
In fact to this day, when anybody asks how I'm doing, I say, gainin' and leave it at that..
