That moment of wrestling with the angel, wrestling with the hard problem, that may not be able to be solved. And yet – it’s full of risk, but it’s also full of promise. That is what hacking is about. That’s what eTech is about. That’s what you are about.
Don’t choose the easy path, don’t just go, where other people are going – saying “Oh yeah, I can make some money doing something like the latest hot thing”. Find a hard problem and try to solve it.
