I've definitely sold some Twitter shares. I don't own as many as I used to, because I'm not an idiot, but I own more than I should because I'm an idiot.

'Shark Tank' has been a sincere joy. As our traditional venture-backed companies get bigger, the investing side tends to get more political and complicated. 'Shark Tank' takes me back to my early days working with ambitious founders in their earliest and scrappiest days. The show reminds me of what I deeply love about this business.

Effective storytelling is the key to getting users to understand and adopt your product as well as imperative to recruiting team members and future investors.

Travis Kalanick was and is the perfect person to lead Uber, a product I knew from day one was going to be big.

A great idea can't succeed without a great operator. But rarely can a great operator squeak by with a bad idea. So, as pithy as it sounds to say 'It's all about the people,' I only invest when I think I have found the right team for the right business.

When I first agreed to do 'Shark Tank,' they asked me to wear a suit, and I was just like, 'No. I can't. It'll end my career.'

I have one of the self-driving Teslas; it drives itself periodically. It's a marvel of science, but it's still frightening. I think we've got a while before regulators and the general public wrap their heads around the path that will lead to the ubiquity of driverless cars. There's no doubt Uber will be a leader in that space.

Ride-sharing is one of the biggest math problems that's ever been approached, that's ever been attempted to be solved.

Uber has an information advantage, a computational advantage. There's massive structural advantages to the player who's smartest about how to deploy cars, where to deploy cars, how to adjust pricing dynamics, how to ensure supply of drivers - the party that understands best the behavior of riders.

I spent a lot of time learning how to define myself internally rather than externally. I learned how to care less about external validation. I think that's given me a renewed confidence in speaking out loud. I kind of don't care what people think about me. I feel a lot more confident in saying what I believe.

One of the things that struck me is how authentic 'Shark Tank' is. I don't know how more real it can be. You have no prior knowledge about the entrepreneurs.

I have learned a ton about inventory, co-packing, wholesaling, end caps. All these concepts are easy to breeze by in what I do for a living or assume that there is a marketing manager or specialist in one of our companies that handles that.

I'll miss working with Mark, and all of the other Sharks. Each of them has been incredibly generous and warm to me, and I am proud of all the episodes we made together.

George Winston piano albums have been my go-to since junior high.

If Trump publicly commits to embrace science, stops threatening censorship of the Internet, rejects fake news and denounces hate against our diverse employees, only then it would make sense for tech leaders to visit Trump Tower.

I succeeded at venture capital because, for years, I rarely thought about or spent time on anything else. Anything less than that unmitigated full commitment leaves me feeling frustrated and ineffective.

I'm also launching a podcast. Because, I mean, the world desperately needs another podcast, am I right? Not to be a tease, but the format is different from anything else I've seen out there, and the subject matter is hopefully boundless, eye-opening, and a little cathartic.

Work at a place like Google for awhile: if you do an interview and you say all the right things, no one really cares. But the day you say the wrong sentence, it's attributed to 'Senior Google Executive,' and the stock moves, and everybody hates you.

In the earlier years of my career, I made my own attempts to fit in and be accepted as one of the tribe of Sand Hill Road guys.

I have definitely refocused Lowercase Capital on later-stage deals and my existing portfolio.

American computer science grads often have very little exposure to the human condition. They've rarely had manual labor or service jobs. They grow up in a bubble of privilege lulled into thinking this country is a true meritocracy.

2009 was one of the busiest, most insane, stressful periods in my entire career. I was raising a bunch of money, buying a bunch of Twitter. I saw my friend fired as CEO of Twitter. Uber was growing like a weed. As these companies get bigger and bigger, there's more and more friction. Being public was the last thing I wanted to do at the time.

When you get into investing, your default stance should be 'No,' because most deals suck. Most deals won't make money. Most companies will fail.

There is a greed case for diversity. Diverse perspectives bring us into markets we didn't know existed.
