Just a note: It hasn’t always been so, and it may not always be so, but right now I’m at a stage in life where I’d rather do work for free than for a token amount of money… And I’m much more inclined to accept such offers from people who need it than those who don’t.
That is all.
I kinda know how you feel. For personal computer work, if it isn’t worth doing it for free it isn’t worth doing. Generally, this is because time is too valuable.
