Until you draw your last breath, always understand that you have not lost the war. You can still forge ahead and make your life a success.
No matter what happens as long as you can communicate you can continue to make the world a better place. Serve yourself by serving others. Be good to others and build genuine relationships, and enjoy life.
Don’t think that you have the answers, or that you don’t need to learn anything else. Life is dynamic, and you need to be too.
