Recognize that there will be failures, and acknowledge that there will be obstacles. But you will learn from your mistakes and the mistakes of others, for there is very little learning in success.

One of the things I benefited from when I started this business was that I didn't know anything. I was just instinct with no preconceived notions. This enabled me to learn and change quickly without having to worry about maintaining any kind of status quo, like some of my bigger competitors.

I'm pretty active anyway, but I'm also competitive.I used my Fitbit as an example of the innate power of data to turn information into insights and actions.

Don't spend so much time trying to choose the perfect opportunity, that you miss the right opportunity.

We've found that customers are very open. They'll tell you what's going on, what's working and what's not. They're looking for help.

Collaboration equals innovation.

I have no doubt that in the future, wearable devices like Fitbit will know my blood pressure, hydration levels and blood sugar levels as well. All of this data has the potential to transform modern medicine and create a whole new era of personalized care.
