What are your productivity hacks?
jwecker: In addition to other suggestions, I would suggest the pomodoro technique if you're in an environment where you deal with reactive/disruptive work mixed in with focused work. http://www.pomodorotechnique.com/Depending also on the variance of your work- if there is work that requires lots of contexts (phone-work vs. appointments vs. programming vs. design...) there's always Getting Things Done (GTD).  I would also recommend GTD if you deal with lots of incoming data-streams, paperwork, or if you are generally unorganized.
