Do you exercise? It is beneficial for your body, but you can exercise in such a way that accomplishes nothing else, or you can work. Do you understand the importance of keeping your mind active and engaged? You can accomplish this by working word or number puzzles. Can you complete the implied logic above? Can you exercise your mind in such a way that it produces a beneficial result other than just being engaged? Try seeking out thoughtful and reflective people who differ with you on important issues. Invite them to present their arguments, and do the same for them. If you persuade them you will have accomplished something. The same is true if they enlarge your understanding.
