Make this your mantra : "I'll do it later. There's more time."

Come up with things you ought to do three weekends ago. If u cant think of any, these may help :-
a) 'My table is too dusty. I cannot study in these conditions thus I should dedustify.' Take at least 3 hours to "find" the duster before you start dusting.
b) 'Whats that song i need to download again?' Hmm... Switch on your laptop and get carried away.
c) 'My socks are not organized. I MUST search for my other purple pink polka dot pair.' and
This never fails -
d) Ask your parents if theres any cleaning to do. Quite beneficial as this is major sucking up and you'll prolly end up with a brand new car by the end of the year.
