sorry to sound preachy, as you know you cant edit after a while .! My house is full to the rafters of unsold work.

I did not take it that way, thanks for relating your experience. I understand about extending effort and time where there may be limited or no return, but if one measures actions solely by the return, there seems little purpose in anything. Besides, "return" can be many things, not just money of course. Experience and learning are huge returns, in my opinion.
