Remember,  your assumptions are just that... assumptions. They can be very  helpful. Yet they can also cloud your judgment. Don't get so comfortable  with your assumptions that you forget about them. They have a powerful  influence, and it's your job to make sure they're in line with reality. Conditions change. The assumptions you  developed when you were a child, probably no longer apply. Yet you may  still be basing some decisions on them. Priorities change. The  assumptions you depended on when you graduated from school, may no  longer reflect what's important to you. The marketplace changes. The  assumptions that led to last year's sales increase, may no longer be  valid. When you have a  decision to make, remember to examine your assumptions. Think about how  you've grown, and how you've changed. Don't base today's decisions on  yesterday's assumptions.
