success - Turbo Coach, achieve breakthroughs - Brian Tracy

THE MOST IMPORTANT OF ALL productivity skills is effective
and efficient use of your time. Three simple rules can
ensure that you earn the highest possible return on your time:
1. Put more time into high-value activities and less or no
time into low-value activities.
2. Begin doing new, highly productive things and/or stop
doing old, unproductive things.
3. Put as much time as you can into those activities that
are important and/or urgent.
