Every day I work on my main project, I clear my desk completely, take out a small notepad and write my overriding goal, and my next step goal, and then make a list of tasks for that next step goal.

Then I work.

Writing the major goal every day is important to not let sub-goals overshadow it. Writing the immediate goal every day is important because together the two goals create a very clear direction of action with a clear next step.

I have my screen mounted on the wall, and have side end-tables for pens, papers and notes I need, etc. so my desk is absolutely clear.

My desk is a half circle, but not that deep, because that optimizes the usefulness of the surface for work (not storage).
