Probably the biggest impact for something less than $100.00 would be a mole skin diary. I’ve got them all lined up for every year. I’ve had them since 1986. So, in there, in a very tactile way, I have like lists in the back, movies, books. And then, I write in the back the name of the book and then who recommended the book.

Yeah, two things pop up. One is this $11.99 book that my wife bought my son and he won’t put it down. I have an eight-year-old son. ... Any little book that I give my son feels like the greatest gift in the world because he becomes mesmerized by the imagination and the stories inside of it.

I have the question ready right here. I bought a skateboard about two months ago, which has a funny story in itself. ... I used to skateboard back when I was a kid, but literally had not skateboarded in 20 years.

Well, you know, I would probably point us to a beautiful Pinot Noir from Joseph Swan up in Sonoma County. You know, it’s like the artwork of Andy Goldsworthy or anyone who delights in anything ephemeral.

Our culture lionizes entrepreneurs who navigate daring switchbacks in their career. Steve Jobs was admired not just for Apple, but also his detour to found Pixar. Elon Musk is revered for helming Tesla AND SpaceX. But don't be distracted by other people's winding paths. I believe you should celebrate your single-mindedness, and stick to your own overarching idea — for as long as it holds your own fascination. In my experience, that could last your entire career.

Obvious I give out my own books fairly often: The Startup View , The Alliance . Recently I’ve been giving out another book of friend of mine, Joshua Cooper Ramos, The Seventh Sense .

Well, that all comes from your network. And so even today with, well over 300 million people on LinkedIn, most people have yet to learn how to use their network, in order to ally with their network, in order to find the right economic opportunities. And that’s one of the things that I’m still working on.

The challenge of a big, over-arching vision is that it's hard to know where to start. And your biggest opportunity will change from year to year. Technology changes. Competition changes. You change. My advice: Just start. Find a single unmet need that nudges the world closer to where you believe it's going. And if you hit a dead end, pivot.
