All modern investors serious about their long-term outcomes should consider the various forms of available pre-commitment strategies. Significant evidence shows that investors who avail themselves of auto-investment strategies in their workplace retirement programs tend to save more and do better over time.168 The routine is particularly useful dur

People who have more money are not necessarily happier—though some are. If anything, money alleviates sadness more than it inspires joy.
