Procrastination is the bad habit of putting off until the day after tomorrow what should have been done the day before yesterday. - Napoleon Hill 

If you do something today, it is done. If you say, "I'll do it tomorrow," you are likely to put it off another day, and another day, until Later becomes Never. Choose!
