Dexter Holland, front man of The Offspring and a PhD molecular biologist, drops a much needed message in this commencement speech to USC graduates:

… after you leave here today, you’re going to be asked, “What are you going to be?” As if you can truly be only one thing for the rest of your life.

I hope you reject that premise. I hope you find your dual life, that you harness the gravity of your aspiration because the gravity that pulls you also grounds you. I hope you never feel forced to trade your aspiration for a paycheck or your passion for a title. I hope you find the space to be both a rigorous thinker and a wild dreamer.

We solve the world’s most complex problems with a scientist’s precision. But we also need people who can see the world through an artist’s eyes and heart. #

Fitter Happier: Explore your Apple Health data. I wanted a fast, local way to analyze the years of Apple Health data I’ve accumulated. So I built Fitter Happier, a little tool to explore my workout and health trends without sending it all to the cloud. If you’re nerdy about your data, you might enjoy it too. It’s open source. Fork it, tweak it, make it yours.

The Most Important Thing

A few years ago, I came across a quote while listening to an interview with Zita Cobb, a Canadian business leader turned social entrepreneur. She cited this quote from a former boss as part of sharing lessons in building the truly one-of-a-kind Fogo Island Inn.

Someday I’ll Miss the Chaos

The toys litter the room, kids shout too loudly in the car, and the clothes pile up unfolded. But one day the rooms will be tidy, the car rides quiet, and everything will be in its “right” place.

The Harvest Backstory

By 2002, the dot-com bust and the general economic downturn had wiped out most technology companies that had thrived just a few years prior. The internet consulting company I worked at was on its last legs before it too would be dismantled and sold. I would soon be laid off...
