I hate phone calls so I believe in a telephone armistice. To me, the idea of calling someone unprompted is basically saying, 'Hey, stop whatever you're doing and talk to me right now.

I think everyone should learn how to code.

Even if you have no interest in starting a company, having the experience of having ideas and doing them, that's muscle to exercise because that's what people are going to want to see. That's what makes you different.

The first version of everything is janky.

You know that Estonia, based largely on how successful Skype was, built by Estonian developers, that was a tenth of the entire country's GDP when eBay bought it. That was like a decade ago, it was f****** Estonia, they were behind the Iron Curtain two decades earlier. They're now pushing for K-12 education in computer science in public schools. They've gotten the message. They know how much value that can bring.

At the end of the day, how many ads did it take to convince you to use Facebook or Twitter? It wasn't marketing or advertising that convinced you to use these services. It was their value.

Obviously solving the education problem is big and complex, and there's already so many failings, but coding is the new fluency. This is the most valuable skill of this century. If you want to be a founder of a company, and not even just a tech company, but like a founder of a company, because I'm telling you software is going to play a role.
