Warren Buffett Quote
I wouldn't mind going to jail if I had three cellmates who played bridge. … The approach and strategies [of bridge and stock investing] are very similar. In the stock market you do not base your decisions on what the market is doing, but on what you think is rational. With bridge, you need to adhere to a disciplined bidding system. While there is no one best system, there is one that works best for you. Once you choose a system, you need to stick with it.
