On procrastination & perfectionism

Found this gem via twitter where the author attempts to analyse why he procrastinates and how it makes him effective.

Especially like this post where he relates perfectionism and procrastination:

The fantasies of perfection of replaced by the fantasies of utter failure. So I finally get to work on it. Now it would have been simpler for me, and for the publisher, and for the author, if I had sat down and spent four or five hours on the manuscript right off the bat. If only I had been able to give myself permission to do an imperfect job right at the outset. Is there anyway we can bring that about?
