We need to give women the freedom and confidence to believe and be whatever they want to. This isn't just about business, but about social conditioning in all cultures.

Don't become paralysed by anticipating the unexpected. It does not pay to be worried about failure. If your mind is crowded with thoughts of what could happen, you will never achieve your best performance.

The more you do it – the more you build a mental scar tissue that you can lean on – That's the 'stuff' that lets you pick up the pieces and go again.

In space, you can only worry about the things you can control – not the constant low-level simmering danger that you might explode and die. If you worried about that, even a two-week flight would be hell, never mind a 200 day one.

To me it was an adventure. I'm a hardened explorer and adventurer, and I remember the whole mission as an adventure with some awesome experiences and beautiful sights.

In my book, the reason I call figures like Stalin, Mao, Pol Pot, etc., red leviathans is that they're actually serving a role that's necessary in a modern progressive revolution: they're the ones who say what is revolutionary and what isn't. Because it turns out that's not an easy question to answer.

Jade Begay, an indigenous woman with roots in a tribe in Mexico, shares a powerful sentiment from her culture: 'What if our best times are ahead of us?' This question challenges us to adopt a more hopeful and forward-thinking mindset, one that can inspire and motivate us towards positive action.
