I think procrastinators are people who cannot delay gratification. They must do or have what they like first, before they get on to doing or getting what they should. Whether it is a sensible move or not to procrastinate, they are not bothered by it and prefer to deal with the consequences when it happens. As some Chinese saying goes, these people will only "dig the hole when they need to sh*t".
Well Anna, some people are like that, so instead of getting frustrated, count to 10 and smile. Variety is the spice of life. The world will be a boring place if everyone is anal like me.
