Consistency
Airbnb is different from most brands. We're a community of individuals, and yet there's a consistency holding us together through the values we share. We have a common belief in belonging, but everyone's expression of it will naturally always be a little different.
I have always wanted to learn the piano, but because I travel so much, I can never get any consistency of lessons. So everywhere I go, if I can find a piano, even if it is in the lobby of a hotel or something, I go on YouTube and pick some songs to learn.
One isn't necessarily born with courage, but one is born with potential. Without courage, we cannot practice any other virtue with consistency. We can't be kind, true, merciful, generous, or honest.
Success isn't always about greatness. It's about consistency. Consistent hard work leads to success. Greatness will come.
