"Value investors have to be patient and disciplined, but what I really think is you need not to be greedy. If you’re greedy and you leverage, you blow up. Almost every financial blow up is because of leverage."
“As Graham, Dodd and Buffett have all said, you should always remember that you don't have to swing at every pitch. You can wait for opportunities that fit your criteria and if you don't find them, patiently wait. Deciding not to act is still a decision.”
