I am really impressed by lawyers who write books and tell us that they never lost a case. Most lawyers who have never lost a case have not had enough hard cases. But there are very difficult cases out there.
I really don't think life is about the I-could-have-beens. Life is only about the I-tried-to-do. I don't mind the failure but I can't imagine that I'd forgive myself if I didn't try.
Success or failure depends more upon attitude than upon capacity successful men act as though they have accomplished or are enjoying something. Soon it becomes a reality. Act, look, feel successful, conduct yourself accordingly, and you will be amazed at the positive results.
