I just want to build world-class software for world-class people.

I’ve realized that work is the only thing that gives me a sense of excitement and stimulation.
What about you? Where do you get that feeling when you’re not working?

Ray Dalio:
I believe success is a matter of having meaningful work and meaningful relationships—work and relationships that you are thrilled by. If you can make your work and your passion one and the same, and you can do it with people who you care about and care about you, you will have a happy, successful life.

All I can say is, I'm really exhausted.
