Start all of the pieces of work a little bit earlier. The key to starting work early is not succumbing to the pressure of having to finish the work. Don’t worry about finishing. If you’re a developer, you can start doing things while your design or information architect are working because a lot of your work actually isn’t dependent on their work. Some of it is, so you probably won’t be able to finish, but that shouldn’t stop you from starting.
Share Work-in-Progress Early and Often
When you share work-in-progress, share it with the caveat that no feedback is needed at this point. You’re simply sharing it to let people know where you are. For example, if you have to make 12 wireframes, share it when you finish 2 or 3. Rather than spending a whole week to drop 12 wireframes, share 2 – 3 wireframes every 2 days. The more often you do this, you start to build rhythm, and rhythm builds momentum.
There are three variants of procrastination, depending on what you do instead of working on something: you could work on (a) nothing, (b) something less important, or (c) something more important. That last type, I'd argue, is good procrastination.
That's the "absent-minded professor," who forgets to shave, or eat, or even perhaps look where he's going while he's thinking about some interesting question. His mind is absent from the everyday world because it's hard at work in another.
You can't look a big problem too directly in the eye. You have to approach it somewhat obliquely. But you have to adjust the angle just right: you have to be facing the big problem directly enough that you catch some of the excitement radiating from it, but not so much that it paralyzes you. You can tighten the angle once you get going, just as a sailboat can sail closer to the wind once it gets underway.
