I’ve met people who had every advantage and others who began life with less than nothing. Some of them are successful and happy; some aren’t. Talent and intelligence helps. Being organized, hard-working, and determined have incredible merits.
However, only one personality trait stands above all others as a universally common predictor of success and happiness: resourcefulness. The ability to take however much (or little, as the case my be) and squeeze every last drop of value out of it is what matters most. Every successful and happy person I know is also resourceful.
Opportunity is everywhere. It doesn’t come to those who wait, nor does it come to people who work their asses off. Opportunity, and its fruits, belong to people who see, recognize, seize, and mold it for all it’s worth. Turn over every rock and make the most of everything you find. Be resourceful.
