I guess people usually procrastinate because...

It's someone else's idea, not theirs, and they really don't want to.

They'd rather do something more enjoyable at the moment.

They're avoiding.

They're afraid.

They have their minds on something else.

They're resentful.

They're demonstrating their independence.

And so on...

It's a really tough one to beat. I've had lots of trouble with procrastination. Writing down "to do" lists, and crossing them off as they get done definitely helps, though.
