The second thing there was another thing I learned at Sequoia is that the culture of a business is built in the first six months by the first ten to 15 employees. These are magical, really, really important times. And I used to hear a lot even at Sequoia, a lot of entrepreneurs saying, “Hey, I'm too busy to think about culture. When we become a unicorn, when we grow, I'll worry about culture.” And for whoever has kids, it's almost like saying I'm too busy about educating my kids. When they turn 18, then I'll figure it out. Too late.

I was going to say work on what you love, but that's not really it. It's so easy to convince yourself that you love what you're doing — who wants to admit that they don't? When I think about it, the happiest and most successful people I know don't just love what they do, they're obsessed with solving an important problem, something that matters to them.

Yes, but not with a formula. So there are many, many efforts now to decentralize and they create a rigid formula and give people rules from on top and say, 'Now it's yours.' And that isn't worked very well either. … And, you think about the variety. If you look at a countryside, think of the variety out there in terms of the ecological variety.

I think it's something that nobody's really talked about in the past because we're supposed to be this big, macho, strong person that has no weaknesses. You know, we're supposed to be perfect.

I know it is utterly fanciful to expect professional cricketers to play the game like amateurs; but the trick, I believe, is taking the spirit of the amateur - of discovery, of learning, of pure joy, of playing by the rules - into our profession. Taking it to practice or play, even when there's an epidemic of white-line fever breaking out all over the field.

One of the biggest challenges that the game must respond to today, I believe, is charting out a clear road map for the three formats. We now realise that the sport's three formats cannot be played in equal numbers - that will only throw scheduling and the true development of players completely off gear.

One of the things, Bradman said has stayed in my mind. That the finest of athletes had, along with skill, a few more essential qualities: to conduct their life with dignity, with integrity, with courage and modesty. All this he believed, were totally compatible with pride, ambition, determination and competitiveness. Maybe those words should be put up in cricket dressing rooms all over the world.
