“You have a day to spare and wish to use it well. You see yourself in a kind of compartment of time whose immediate walls are last night’s and tonight’s sleep. Look beyond these walls and back at the present from imaginary mirrors placed in the past and the future. Think of the choices and events which brought you where you are; think of what you once wished or expected to have achieved by this point. Imagine what you will think of this period some time in the future. Will you think or do anything today that is worthy of future memory? Try to make the present memorable; or, failing this, review daily what is important about the present period in your life. In so doing you will enrich time.”
