Simple time sheet
Update, due to lack of interest the time sheet generator is no longer available.
You might know Professor Randy Pausch for his Last lecture. Professor Pausch also gave a talk about Time Management. The talk is a synthesis of methods and advice gathered in books and in real life. One advice is about Time logging. Logging time does not take much effort and will help you track down time spent doing things that are not important and that take away lot of productive time.
I recently tried to get a simple printable time sheet on the web. After researching during 1 hour I could not find anything usable. Therefor I wrote a simple time sheet generator (No longer available).
The generated time sheets are very simple. There is no category; just write what you do. Splitting hours into categories comes after getting enough data.
