There's something special about San Francisco. Not just the fact it's a lovely city with a winter climate to die for. It's a melting pot of ideas. Full to the brim with smart people who want to make the world a better place.
Sounds a bit worthy that, so I'll qualify it by adding that most of the ones who are successfully making the world a little better are doing so and earning big bucks too.
In four working days my colleague Nick and I have had some brilliant conversations with people who frankly were it not for us working for Walmart wouldn't have spared the time.
But once in their company they couldn't have been more accommodating.
We've had our brains stretched by clever engineers, our ideas entertained by seasoned entrepreneurs, and our vision endorsed by people who have been there, done that, and invented the T-shirt never mind bought it.
It's a huge privilege to get the chance to travel here for work.
But every trip pays back in spades.
Not only does it help calibrate your thinking it also enables you to reflect, connect, and make leaps forward.
I'm really excited by the year ahead. If only half of the things we've discussed this week materialise it's going to be an awesome* year.
*Apologies for using the A word but I've been in California a week now you know :)
