You make your own happiness. Happiness is a state of mind. Simple example, talk to a boxer, who loves boxing, about what it feels to be in the zone while getting hit or hitting someone in a match and she will tell you that she is as happy as she can be. Most of us think of that as the definition of hell. If you expect someone else to care more than you then you're in trouble. No one, not a company, not a boss, not a friend cares about you as much as you do.
Amazon is doing its best to be number one. That's the goal. Everything else is just a byproduct of that goal. Do you think they care about your happiness above that? The answer is no. The only one I know is happy is Jeff Bezos. Everyone else is a question mark.
