You may also be surprised to find that some of the things you write on the list will actually come to pass, almost without your making any conscious effort to make them happen. If you acknowledge the power of the imagination to foster changes in perception and performance, it’s easy to see how having a Someday/Maybe list out in front of your conscious mind could potentially add many wonderful adventures to your life and work. We’re likely to seize opportunities when they arise if we’ve already identified and captured them as a possibility.
