Procrastination - “is a behavior which is characterized by the deferment of actions or tasks to a later time” and its better explained here.
A funny example is in an excellent you tube video her

The problem
---------------
I truly believe that procrastinate because of most importantly the lack of focus among many other reasons.
I procrastinate because I think even if I study, I wont get anything and there is no point spending time..there is too much to study. Even if I start I wont be able to study a lot and if I don't, there is no point studying.

This is how I try to overcome this?
---------------------------------------
- Study short items and not too many items and be aware that you have studied them and take 15 minutes in a day to remind them to yourself.
- Do not think that you have studied less at any point of time.
- Get the gist of the short items and get that as fast as you can.
- Take frequent breaks.
- Do not think of anything while studying irrespective of whatever it is about.
- Think whatever you are doing now is moving you towards your goal and the goal is that short item you are focusing on and studying.

N.B. :- The funny thing is I procrastinated for writing this blog entry itself for 3 days. :-) See the point I am making above. ;-)
