"J.P. Morgan once had a friend who was so worried about his stock holdings that he could not sleep at night. The friend asked, 'What should I do about my stocks?' Morgan replied, 'Sell down to your sleeping point' Every investor must decide the trade-off he or she is willing to make between eating well and sleeping well. High investment rewards can only be achieved at the cost of substantial risk-taking. So what is your sleeping point? Finding the answer to this question is one of the most important investment steps you must take."
