Procrastination, Distractions, Loss of interest...

You rush to get something ready for 'them' - then 'they' change their mind or decide 'they' don't need it...
If you're slow and haven't done it the change isn't so traumatic and if it's scrapped then there's no wasted effort !

This can backfire though. I'm currently rushing a model that a client decided they didn't need a few months ago. At the time I didn't care as I hadn't actually done it. A week ago he decided he does want it, I've procrastinated all week, now I need to finish it for tomorrow morning.

But the adrenaline rush.... aaaah...

Not there unless you have prevaricated...
