What Rodrigo told me about surfing: ‘At low tide Uluwatu, if you’re not 100% confident you can get the wave – don’t go.’

Here’s the thing: you can never be 100% confident. Of anything. But if you’re 90% confident – you take that and act as if you’re 100% confident. And you go all out.

The going all out will give you the extra speed to get on the wave in time to make the drop.

Same with business. You plan as best you can – do your due diligence. Then – when you’re 90% confident you can make it, you act as if you’re 100% confident – and go all out.

That creates a margin of safety – and focuses you to perform at your best.
