What are you currently reading?

So many books! "Why We Sleep," "Eat & Run," "Humour, Seriously," "Encounters with the Archdruid." Generally, I'm reading 5-6 different types of books at any time.

Where have you lived or visited that most shifted your perspective?

India. Such an epic mix of sounds, colours, smells, experiences. There are thousands of years of humanity all bubbling together within a beautiful setting amongst wonderful, interesting people. It can also be a very difficult place to live with tough problems to solve. I love it more every time I visit.

What was your most
painful learning about
entrepreneurship?

You must be absolutely obsessed with the
problem you want to solve. If not then you’ll never have the grit necessary to keep putting one foot in front of the other when times get tough. A deep mix of passion and perseverance is critical for success (and fun).

What is your “happy place?"

Lake Tahoe, California. It made me fall in love with nature and seeded my obsession with the mountains. The smell of pine mixed with dry Sierra dirt is still my favourite scent in the world.

What one piece of advice
has most resonated with you throughout your career?

I’m going to give you two. The first was from the earliest manager of my career who told me to never present a problem without also providing a solution. The second is more of a life and career mantra: “go confidently in the direction of your dreams.” Always taking a step towards what I believe in has resulted in amazing work, an inspiring community, and a wonderful family.

What is one thing you love that most other people may not?

Eating vegetables for breakfast- I crave them in the morning! In many cultures it’s totally normal but I’ve been the recipient of many curious looks when I down a huge bowl of salad or some butternut lentil soup as my first meal.
