Five Basic Rules from Warren Buffett
"You need to have a steady temperament to not follow the crowd and not be against the crowd."
"Investing is not a business where you conduct surveys, it is a business where you reflect."
"The real test of whether you are investing in terms of value or not is whether you care about whether the stock market opens tomorrow."
"If you make good investments... you shouldn't be worried if they close the stock market for five years."
"Stock prices don't tell me anything about business. The numbers in the business tell me something about it, but not the price. I would prefer to evaluate a stock or a business first and not even know the price so that it doesn't affect me."
