Anticipate problems, traffic jams, slow elevators, and getting a little lost. Plan extra time for appointments so that you plan to arrive at the building ten or fifteen minutes before your appointment and more if you are not familiar with its location. If you arrive early, you'll have time to use the restroom, get a drink of water, gather your thoughts, and present yourself in a calm, relaxed way at the appointment time. If you are late out of habit, mercilessly extinguish this habit. Don't change your watch ahead fifteen minutes or lie to yourself about the time to get yourself to hurry.
Every day has unavoidable delays, waits, and time between events.
Use these scraps of time for useful contemplation or work that can benefit you. Think about your day's plans or take out a pen and paper and rework your shopping day list. Take along a book to read. Do the clutter purge on one section of your desk or countertop. Scraps of time, mined for their benefit to you can accomplish useful work that you would otherwise have to do some other time.
