You should be unconcerned about short-term price action when you own the securities directly, just as you were unconcerned when you owned them indirectly through BPL. I think about them as businesses, not "stocks", and if the business does all right over the long term, so will the stock.
Warren BuffettThe value of market esoterica to the consumer of investment advice is a different story. In my opinion, investment success will not be produced by arcane formulae, computer programs or signals flashed by the price behavior of stocks and markets. Rather 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.
Warren BuffettThe most important investment you can make is in yourself. Very few people get anything like their potential horsepower translated into the actual horsepower of their output in life. Potential exceeds realization for many people...The best asset is your own self. You can become to an enormous degree the person you want to be.
