You should have a fund of knowledge of something and out of that you make up you mind.
Go into something because you really like it, and then do it with a drive and enthusiasm so that it isn't work.
I wouldn't write a book, because saying the word I over and over again would nauseate me.
Money is not a fund of knowledge.
My philosophy all my life has been the pursuit of excellence.
I don't think I have ever worked in my life, because work to me means that you are really doing something that you don't like.
