It’s a tactic, used for both good and bad. When a problem arises, ignore the problem and focus like a laser on improving your own skill. If you are a mechanic, ignore the riots and read a shop manual. If you’re a manager, ignore reports of election fraud and re-read “Who Moved My Cheese?”. If you work in food service or a factory, focus on your hobby. Focus on your own attitude.
Some people do this to a fault. They improve themselves so much that they ignore the problems of the world. Good or bad, self-growth makes people that strong.
