Procrastination

Why do we tend to procrastinate so much in our day to day lives? I am so guilty of this but I am trying so hard to do better. Do you find yourself putting things off until a later time when you know they really need to be done? What is it that we really gain when we do this if we still have to eventually get the task completed anyway? Sometimes I guess we can justify it if the reason we are putting off the task is a really good one. Maybe like, in place of getting that oil change, opting to go to an event or occassion that is only happening at that specific time and you just cant miss it. I'm talking about like a graduation or something. But then doesn't that mean that our bigger problem is time management? Hmmmmm.......
