Excerpt from Buffett's Thank You Letter Don’t beat yourself up over past mistakes. At the very least, learn something from them and keep moving forward. It’s never too late to improve yourself. You’ll never achieve perfection, but you can always get better. Greatness doesn’t come from amassing huge wealth, winning widespread attention, or holding government power. When you help others in any of the countless ways possible, you’re helping the world. Kindness is incredibly precious. Find the right role models and follow their example.
