Never miss an opportunity to learn another life skill. Just because you are an author or a doctor does not mean that you cannot learn carpentry, auto mechanics,electrical wiring, farming, or any other discipline. Each of these skills will give you the opportunity to help someone and to make a friend. Your new friend probably has a skill that you do not. If you will just ask every skilled person you see to show you how he does what he does, you will have the tools to succeed in life, to make new friends, and to save a boatload of money.
