• How much time did I spend on activities that someone else could have done

(perhaps with some training)?

Before you can take control over the way you use time, you have to understand what you already are doing. A practical way to learn about your use of time is to keep a time log, a record of what activities you are doing hour by hour throughout the workday.
Figure 13.1 provides an example. Each half-hour during the day, write down what you did during the previous half-hour. Do not wait until the end of the day; this level of detail is too difficult to remember.
