Master Your Time in 10 Minutes a Day resource page
One morning from my time journal

You don’t have to write down every detail. Again, for this to become a sustained habit, you need to do it in a way that works for you.

I used abbreviations for common activities to make the process faster. What you see above is the version translated to common language, to make it understandable. The start time of an activity is taken automatically from the end time of the previous activity by an Excel formula. Another formula calculates the activity’s time span. It saved me time over inputting this manually.

Nuts and bolts

See the “time tracking” entries? Those are the points when I turned on the computer on a train and at the office (5:57 and 7:30 respectively) and rewrote the entries from my pocket notepad into an Excel sheet. After 7:34, I hardly needed any time dedicated solely to time tracking, as it was just a matter of changing the window on the computer, marking the time and jotting down an activity name.
