The last thing you want to do, unless it's a very unusual situation, is to invest money.
You should have a fund of knowledge of something and out of that you make up you mind.
Money is not a fund of knowledge.
Go into something because you really like it, and then do it with a drive and enthusiasm so that it isn't work.
Work isn't really work for me. I hate to tell you this, but I've never liked the weekend in my life. I was enthusiastic about Monday morning from the day I left college.
My philosophy all my life has been the pursuit of excellence.
