Investing is driven by two kinds of emotions, these are fear and greediness. If everyone is greedy you should have fear. If all are feared, that is the time you should be greedy. One should be patient to wait the right timing. Be like a crocodile, how patient he is. He opens his mouth for a long period of time, patiently waiting for a victim. He is not impulsive. He knows when he can make big profit.
