Everybody has a purpose on this Earth
Everybody has a purpose on this Earth. It may be difficult to identify or determine your purpose but whatever purpose you have you should use for helping people. Your purpose is generally those skills that you are really good at. So use those skills to identify and create fulfillment through utilizing your purpose.
— from Before Takeoff (front matter)
In the book
The great and glorious masterpiece of a human being, Montaigne said, is to live with purpose — a purpose unifies a scattered collection of days into something whole the way a single theme turns separate notes into a symphony. Everyone has such a purpose; it is usually hidden inside the things you are genuinely good at, and the surest way to use it is in the service of other people. Spend your hours with care, because of all your resources — knowledge, energy, money — only time cannot be replenished, which makes it the most valuable thing you own. — Before Takeoff (front matter)
