I feel that procrastination is a result of laziness and potentially a fear of being unworthy or no good at what you're working on. I don't think its a good idea. Wouldn't you rather just get it done and out of the way even if you finish it quickly? You do bring up a good point that not all works need to be nurtured, but why take the risk? I too have been a huge procrastinator in school, but when it comes to my poetry I take my time with it and produce the what I feel is my best. It's never failed me even if I write it in no time at all.
