Be the example you wish you had.
Be the leader you wish you had.
Be the friend you wish you had.
Be the parent you wish you had.
Be the neighbor you wish you had.
Be the mentor you wish you had.
Teach what you wish you had known.
That's how you actually change the world.
In a world where lots of people talk about it...
Be the one who lives it.
It's the most important, valuable, and impactful thing you'll ever do.
