Whatever business you're in - it doesn't matter - it's going to commoditize over time. It's going to devalue. You've got to keep moving it to a higher value.

As I say to our own team: 'Never protect your past, never define yourself by a single product, and always continue to steward for the long-term. Keep moving towards the future.'

You've got to keep reinventing. You'll have new competitors. You'll have new customers all around you.

Whatever happens, I'll just keep moving forward. Like an avalanche.

My message is - keep moving. If you do, you'll keep arthritis at bay.
