Assess your vulnerability to sin -- Envy: the stock is not always greener in someone else's portfolio -- Vanity/pride: it goeth before a fall -- Lust: losing investing perspective and inhibitions -- Avarice: even King Midas didn't have the touch -- Anger/wrath: don't get mad, get even (at the very least) -- Gluttony: how not to consume the market before it consumes you -- Sloth: the cost of being lazy -- Sinful situations: be aware of events and environments that tempt investors -- We are all sinners, but some of us can be saved.
