Trading is a crucible of life: it distills, in a matter of minutes, the basic human challenge: the need to judge, plan, and seek values under conditions of risk and uncertainty. In mastering trading, we necessarily face and master ourselves. Very few arenas of life so immediately reward self-development--and punish its absence.
So many life lessons can be culled from trading and the markets:
1) Have a firm stop-loss point for all activities: jobs, relationships, and personal involvements. Successful people are successful because they cut their losing experiences short and ride winning experiences.
2) Diversification works well in life and markets. Multiple, non-correlated sources of fulfillment make it easier to take risks in any one facet of life.
3) In life as in markets, chance truly favors those who are prepared to benefit. Failing to plan truly is planning to fail.
4) Success in trading and life comes from knowing your edge, pressing it when you have the opportunity, and sitting back when that edge is no longer present.
5) Risks and rewards are always proportional. The latter, in life as in markets, requires prudent management of the former.
6) Happiness is the profit we harvest from life. All life's activities should be periodically reviewed for their return on investment.
7) Embrace change: With volatility comes opportunity, as well as danger.
8) All trends and cycles come to an end. Who anticipates the future, profits.
9) The worst decisions, in life and markets, come from extremes: overconfidence and a lack of confidence.
10) A formula for success in life and finance: never hold an investment that you would not be willing to purchase afresh today.
