I am happy if I get 2 good solid 2 hour chunks of programming in every day. The days that I do more than that I find myself spinning my wheels, wasting time, and introducing bugs to the software. The rest of my time is spent on learning, researching, talking to users, and letting my brain unwind.

Here is a way to review where you are truly spending your time compared to where you think you will spend your time. Monday morning sit down and make a list of what you would like to complete during the week. Then put it away and don't look at it until Friday.

Grab a notebook and everytime you start something new during the day write down the time and what you are doing. This should include everything. Check personal email, read personal websites, read tech websites, talk to your cube mate, program on project x, go to lunch, work on new bug Z, talk to user y of new project, etc.

On Friday pull out your initial list and flip through the list of what you did. Compare them and see how productive you actually were. You will probably be surprised and will find things that you can start to change.
