Gary Keller said this quote

Happiness happens when you have a bigger purpose than having more fulfills, which is why we say happiness happens on the way to fulfillment.

~ Gary Keller

You need to be doing fewer things for effect instead of doing more things with side effects

~ Gary Keller

When you strive for greatness, chaos is guaranteed to show up.

~ Gary Keller

It’s important to realize that on the journey to achieving big, you get bigger. Big requires growth, and by the time you arrive, you’re big too! What seemed an insurmountable mountain from a distance is just a small hill when you arrive—at least in proportion to the person you've become. Your thinking, your skills, your relationships, your sense of what is possible and what it takes all grow on the journey to big. As you experience big, you become big.

~ Gary Keller
