Wisdom in fragments

The fact that you and I are alive is against stupendous odds. One day we will die, and that's sad, but there are people who will never die because they were never born. We're the lucky ones, we get to die. You can only die if you were alive.

It has been said that we went to the moon to explore the moon, but while we were there, we looked over our shoulder and discovered Earth. Seeing the Earth in that perspective upgraded the firmware of all our brains, of everyone's subconscious. Those missions sparked Earth Day, the Environmental Protection Agency, a comprehensive Clean Air Act... So much activism came from seeing that there's no hint of anyone coming to help us from somewhere, that we're here by ourselves on one planet.

People ask why we're spending money on space exploration when we have problems here on Earth. The first reaction I have to this the fact that we've had wars, poverty, and homelessness long-before anyone went into space. It's not accurate to say, 'we're doing space exploration, and that's why we have poverty.' If we stopped space exploration, those problems wouldn't be solved, they haven't been solved in thousands of years.

I don't care about legacy – not because I'm not thinking of legacy, but because I'm thinking about how to make the greatest positive difference in the current moment I'm living in, and not obsessing about how I'll be looked back on. You're setting yourself up for misery if you focus too much on legacy honestly, but if you try and make a positive difference in the current moment of your life, you're doing the right thing.

You can have your best day and your worst day on the same day. There's so much happening at once, and everything happens so fast… the emotional highs and lows are tense.

We characterise our ideal 'Substacker' in affectionate terms – we call them outsider nerds – they're outsiders insofar as they don't fit comfortably in the dominant media structure for whatever reason – perhaps they feel they can do better work outside of it They're nerds insofar as they're especially knowledgeable or passionate about a particular subject area.

Twitter, Facebook and Instagram were play attention games – they reward creators with 'status points,' likes, retweets and quote tweets for example. Those rewards come to those who are best at monopolising attention… that's not the same thing as telling the truth or acting in good faith. The things that get rewarded in those systems are things that provoke, divide and drive outrage – so we end up with a broken media economy that drives us all crazy and doesn't represent the best version of ourselves.

My dad always said you can't win until you don't care. That's how I approached it. My goal was to ski the best I could, as fast as I could, and I didn't care. I would rather crash than come to the finish line knowing I could have done better.

This might sound strange, but I've never been 'afraid.' I've certainly been nervous- very nervous- but I've never been afraid. That's what has allowed me to come back from injuries- I'm not afraid of the consequences. I know the risks, I accept the risks, but I'm not afraid of the risks.

It's only a failure if you don't learn from your mistakes, right? I was always able to find some way of making every adversity into something positive, even if I was physically no longer the athlete I was, I became mentally stronger. I used every adversity and changed it into something positive.

Success are not determined by who is the smartest in the room- it's determined by who's willing to make the sacrifices to succeed. When most people have an adversity they think, 'oh, I can't do this anymore…. I'm not good enough…' what we are taught to think is, 'oh hey, there's a brick wall, what's my way through, over, around or under it…'

My 90 seconds with Picabo changed my life. You'd be surprised how many kids have parents and peers around there who tell them they can't, I want to tell them they can.

I was only 9 years old, but I loved ski racing. I loved skiing in general, and was lucky enough to meet my idol, Picabo Street. I met her at an autograph signing at a ski shop in Minnesota, and I said that's it… that's what I want to do… and this is who I want to be like. From then on, I made ski racing my focus, and my dad helped me create a ten-year plan to make the next Olympics.

We have learned that the things that matter are not the physical, and material things. What matters in life is hope. Tomorrow is not a given, and we must be happy about small things and we must seize the day.

Hope is the only choice I have. What gives me hope is that people are able to find love and humanity in their hearts in spite of everything that is happening here in Ukraine.

If Putin succeeds in Ukraine, it will show that democracy and the world's forces are not enough to stop him. Are we building a world where the rule of law means something? Or a world where the rule of law means nothing, and only firepower counts.
