I have recently been struggling with getting a specific thing done. Not because I can't do it or don't want to - but because the constant delivery deadline is turning into a pressure that reduces the quality of work that I do. Naturally, I don't end up liking what I have just done, and end up eventually taking more time than what it would have taken me originally in a quality and timeframe that I am comfortable with.
It brings to mind the age-old pie-chart between Cheap <> Good <> Fast, which I feel is a little incomplete.
Its possible to do this, but you have to lower your standards of what "Good" means to you.
