Time Sink

People can waste your time.  When it comes to an office environment this rings far too true for many.  Learn to keep people away from your workspace, learn to say no when asked to do something that does not relate to your main goals of the day.  With focus, we could all work 4 hour days and be far more productive than the 9-5ers who constantly interrupt their train of thought with distractions.  Focus on the goal and get it accomplished.
