The reason why worry kills more people than work is that more people worry than work.

I like the challenge of trying different things and wondering whether it's going to work or whether I'm going to fall flat on my face.

Believe in yourself, and the rest will fall into place. Have faith in your own abilities, work hard, and there is nothing you cannot accomplish.

Work harder on yourself than you do on your job.

Live your life, do your work, then take your hat.
