Ideas are fruits of your thinking. But they’ve got to be harnessed and put to work to have value.
Two ways to get mental stimulation are, first join and meet regularly with atleast one professional group that provides stimulation in your own occupational area. Rub shoulders and minds with other success oriented people. Remember, a mind that feeds only on itself is soon undernourished, becoming weak and incapable of creative, progressive thought. Stimulation from others is excellent mind food.
Second join and participate in atleast one group outside your occupational interests. Associate with people who have different job interests broadens your thinking and helps you to see the big picture.
