“An investor will succeed by coupling good business judgment with an ability to insulate his thoughts and behavior from the super-contagious emotions that swirl about the marketplace.”
“John Maynard Keynes essentially said, don't try and figure out what the market is doing. Figure out a business you understand, and concentrate.”
“The time to buy stocks is consistently over time. You should never buy your investments with the idea, 'I have to get a certain return.' You should look at the best return possible and learn to live with that. But you should not try to make your investments earn what you feel you need. It doesn't work that way. The stock doesn't know you own it.”
