How much time do you spend at work doing things that don't contribute to your success? At first, you may say "not much." But ? especially if you haven't used Activity Logs before ? you may be surprised by how much more time you can find.
How to Keep an Activity Log
To keep an Activity Log, download this template, or open up a new spreadsheet and set up the following column headers:
Date/Time.
Activity description.
How I feel.
Duration.
Value (high, medium, low, none).
Then, without changing your behavior any more than you have to, note down everything that you do at work, as you do it.
Every time you change activities, whether replying to email, working on a report, making coffee, or gossiping with colleagues, note down what the activity is, the time of the change, and how you feel (alert, flat, tired, energetic, and so on).
