No fortune has been made without courage and conviction. But many a fortune has been lost pushing luck onto dwindling odds.
Not to bet is a bet. Staying on the sidelines is a bet that doing nothing will produce better results than the risk-adjusted returns of doing anything. Staying on the sidelines demonstrates faith in a future of opportunities. And staying on the sidelines provides much needed opportunities for rest and reflection.
Conviction without follow-through is cowardice*. But patience in times of uncertainty is the beginning of wisdom.
* Those lacking conviction in anything should stay out of the markets.
