Look at performance of the assets

"I bought a piece of real estate in New York in 1992, I have not had a quote on it since. I look to the performance of the assets. Maybe...my piece of real estate have had pull backs, but I don't even know about 'em. People pay way too— way too much attention to the short term. If you're getting your money's worth in a stock, buy it and forget it."- Wareen Buffett
