I tried to follow Ben Graham's ideas.
Don't be afraid to be a loner but be sure that you are correct in your judgement.
Warren is a very good judge of people and he's a very good judge of businesses.
I'm a passive investor. There are people who are very aggressive; they try to buy companies.
When it comes to investing, my suggestion is to first understand your strengths and weaknesses, and then devise a simple strategy so that you can sleep at night!
You never really know a stock until you own it.
