The mark of the superior thinker is his or her ability to accurately predict the consequences of doing or not doing something. The potential consequences of any task or activity are the key determinants of how important it really is to you and to your company. This way of evaluating the significance of a task is how you determine what your next frog really is.
Long Time Perspective
Doctor Edward Banfield of Harvard University, after more than 50 years of research, concluded that "long-time perspective" is the most accurate single predictor of upward social and economic mobility in America. Long time perspective turns out to be more important than family background, education, race, intelligence, connections or virtually any other single factor in determining your success in life and at work.
Your attitude toward time, your "time horizon," has an enormous impact on your behavior and your choices. People who take the long view of their lives and careers always seem to make much better decisions about their time and activities than people who give very little thought to the future.
Think About Your Future
Successful people have a clear future orientation. They think five, ten and twenty years out into the future. They analyze their choices and behaviors in the present to make sure that they are consistent with the long-term future that they desire.
In your work, having a clear idea of what is really important to you in the long term makes it much easier for you to make better decisions about your priorities in the short term.
Determine the Consequences
By definition, something that is important has long-term potential consequences. Something that is unimportant has few or no long-term potential consequences. Before starting on anything, you should always ask yourself, "What are the potential consequences of doing or not doing this task?"
The clearer you are about your future intentions, the greater influence that clarity will have on what you do in the moment. With a clear long-term vision, you are much more capable of evaluating an activity in the present and to assure that it is consistent with where you truly want to end up.
Make It a Top Priority
If there is a task or activity with large potential positive consequences, make it a top priority and get started on it immediately. If there is something that can have large potential negative consequences if it is not done quickly and well, that becomes a top priority as well. Whatever your frog is, resolve to gulp it down first thing.
Motivation requires motive. The greater the positive potential impact that an action or behavior of yours can have on your life, once you define it clearly, the more motivated you will be to overcome procrastination and get it done quickly.
Thinking continually about the potential consequences of your choices, decisions and behaviors is one of the very best ways to determine you true priorities in your work and personal life.
Review your list of tasks, activities and projects regularly. Continually ask yourself, "Which one project or activity, if I did it in an excellent and timely fashion, would have the greatest positive impact on my life?"
Whatever it is that can help you the most, set it as a goal, make a plan to achieve it and go to work on your plan immediately. Remember the wonderful words of Goethe, "Just begin and the mind grows heated; continue, and the task will be completed!"
