Naturalness is the easiest thing in the world to acquire, if you will forget yourself-forget about the impression you are trying to make.
Dale CarnegieCriticism of others is futile and if you indulge in it often you should be warned that it can be fatal to your career.
Dale CarnegieDevelop success from failures. Discouragement and failure are two of the surest stepping stones to success. The successful man will profit from his mistakes and try again in a different way. When you're afraid, keep your mind on what you have to do...if you have been thoroughly prepared, you will not be afraid. We all have possibilities we don't know about. We can do things we don't even dream we can do.
