Just do it!
I have seen many people and myself sometimes stay at one point where we are waiting for the best idea to emerge, best design to come up while we sit there and wait till the last minute and then rush into doing things that we are not proud of. You know what I mean don't you?
Most of the work is tiresome and non interesting but we got to get through that to get to the interesting stuff. So it is better to start off early and finish the mundane tasks that make our routine and then have time for the creative, productive stuff.
Plan your day and make good use of the plan. Have complete attention in the time you can. Like have on hour of your best time, morning coffee time in my case, to answer your mails and set out the tasks for the day. In that one hour, don't have anything open on your laptop, have your phone on emergency calls only and focus on completing the task. I also would encourage you to pick up the toughest task you have for the day and handle it as the first thing you would do for today. Answering that query, completing the presentation, replying to the client or making that report. Whatever you usually put off till the last minute, handle that first. Once you do that, you take taken up the strongest enemy on the table and then you are practically blazing through the rest of the day.
Having a coffee break or a simple stroll during the day also helps. Try it for a week and see how easy your day becomes. So don't keep it pending till the n'th hour. Just do it and finish it off.
