I procrastinate because I dont want to be doing the things im avoiding, otherwise I wouldnt be avoiding them. Pleasure seeking works in both ways, avoidance of those things you dont find pleasurable.
I know it would be better to get my work done first then play. It's not hard to work out. So why do I faff about all day or week then have to work late to compensate? I quite often don't even enjoy procrastination while I'm doing it, never mind the results so why do I do something that I don't enjoy and has no benefits?
When it comes to work, be confident and don't be scared of making mistakes.
