A typical day is broken up into to 24 hours. Some say 8 hours is for rest, 8 hours is for relaxation or recreation and 8 hours is for work. If this is the case, quite often it is not, no one actually uses the 8 hours to their advantage by maximizing on the time.
Start planning your meetings and appointments at odd times of the day. Instead of having your meetings at 11:00 have it at 11:12 or 10:57. By using this tactic you can use the minutes that are seldom used in the day. The time will also stick in most people’s mind because it interrupts their natural flow of information. More importantly people will begin to respect your time because you respect it.
