Focus on Activities, Not Accomplishments By Brian Tracy
The most valuable tasks you can do each day are often the hardest and most complex. But the payoff and rewards for completing these tasks efficiently can be tremendous. For this reason, you must adamantly refuse to work on tasks in the bottom 80 percent while you still have tasks in the top 20 percent left to be done.
Before you begin work, always ask yourself, "Is this task in the top 20 percent of my activities or in the bottom 80 percent?"
The hardest part of any important task is getting started on it in the first place. Once you actually begin work on a valuable task, you will be naturally motivated to continue. A part of your mind loves to be busy working on significant tasks that can really make a difference. Your job is to feed this part of your mind continually.
