Even retail stores begin to tell us when we should change our thinking. Seasonal items are displayed a month or two in advance. Television advertising becomes a mass of commercials telling us what we need to purchase. All of the "one uppers" gather their items in a hurry so they can be the first to display the new season.
A change in season can lead to a change in heart or mind. Teachers begin to think about end-of-the-school year activities. Greens keepers and car wash owners begin thinking about an increase in business. Whatever the change, let it be positive. Have dominion over your mind and force yourself to see the positive outlook on every situation.
