After a decade at a bicycle company, I was only 3 months into a new gig at a health care startup when I was asked to head to SXSW to both check out the scene, and spend 15 minutes speaking to an audience about where health care is headed. It was a remarkable invitation, certain & clear validation that this entrepreneurial idea I’d been invited to build upon was worth exploring. A shift from bikes to health care wasn’t as big as it sounds: I simply moved from the chassis, to the motor. On either side of that man/machine barrier, the human motivation is remarkably similar: live a better life. It’s a simple idea, but there’s a lot that goes into achieving it. It’s subjective, but so are most sources of dopamine and seratonin. And like it or not, those are the only two things you really like. This, as with other things, is evidence that a career shift into science has taught me quite a lot, quite quickly.
