Time is indifferent in a way that is frightening and then quite freeing. The hours pass at the same rate whether they are wasted, enjoyed or spent worrying, and nothing about a bad day earns you a slower clock or a longer one. What goes into them is the only variable available.

Look at one block of today that usually disappears without you noticing: an evening, a free period, the hour after you get home. Decide what it is for before it starts. One decided block a day adds up quickly.
