"If I listened to feedback, I would have quit on the first day."
You're devoting your life to making something important. Something helpful. Something that matters. Mostly, something that hasn't been done before, that's going to bend the curve and make an impact.
If you begin and end with surveys and focus groups, all you're going to do is what's been done before.
We're counting on you to trust yourself enough to speak your own version of our future. Yes, you'll need the empathy to put yourself in our shoes, and the generosity to care enough to make it worth our time and trust. But no, don't outsource the hard work of insight and creation to the rest of us.
That's on you.
