Jeff Goins said this quote

We must wake up. If we are going to find our callings, we must live intentionally and audaciously. And we must be generous. This choice is not an easy one, and it doesn't come naturally, but it's how we were meant to live. It's the only way - I'm quite convinced of this - that we can find the satisfaction we've been searching for, the lives we've been dreaming of. And although there are legitimate health, business, and psychological benefits to generous living, the most important one is this: generosity gives your life meaning.
