It is funny that you would say this; this phrase has been my goal throughout my life. This is the main reason that I became a teacher. This is the reason that my friends call me when they need something done (electrical, carpentry, plumbing... you name it).
When I teach privately, at the end of each lesson I always ask the student if they have any questions. Most of the time they respond that they understand everything they are to work on. Then I'll ask if they have any questions about anything. Some years ago, a student replied, "What is the meaning of life?".
I thought for a moment and replied, "You have only two things you need to do in this life. The first thing is to be happy, whatever that means to you. The second thing is to be a positive force for good with everyone you encounter." For me, that means being helpful in whatever way each person needs.
Your posts are always helpful, and interesting and show great curiosity (a trait that will always keep you young). Thanks again for the post on the strings; I can't wait to check them out.
