If you want to be a millionaire, think like a millionaire; like they say. That's the Warren Buffet strategy. The billionaire investor believes to invest when others are scared of putting out their money and begins to sell when he notices greed in the market. That's what he teaches us to do. That strategy has worked a few times for me too. However, I must confess it's not an easy strategy to adopt. It will test your inner mind to withstand going against crowd mentality.
