Those who have not found their true wealth, which is the radiant joy of Being and the deep, unshakable peace that comes with it, are beggars, even if they have great material wealth. They are looking outside for scraps of pleasure or fulfillment, for validation, security, or love, while they have a treasure within that not only includes all those things but is infinitely greater than anything the world can offer. - Eckhart Tolle, "The Power of Now"
Your work is going to fill a large part of your life, and the only way to be truly satisfied is to do what you believe is great work. And the only way to do great work is to love what you do. If you haven’t found it yet, keep looking. Don’t settle. As with all matters of the heart, you’ll know when you find it. And, like any great relationship, it just gets better and better as the years roll on. So keep looking until you find it. Don’t settle. -Steve Jobs
