“I know who I WAS when I got up this morning, but I think I must have been changed several times since then.” — Lewis Carroll, Alice's Adventures in Wonderland

Make yourself cozy. Pull up a (utilitarian) chair. Have a refreshing glass of water.

This is an every-two-week letter for product builders. We’ll talk about product & design, leadership & team, and the way we grow and evolve.

Who am I? I started building products as employee 100-something at Facebook and went on to head up product design for the FB app for many years. I’ve kept this blog about design, technology and leadership for a good chunk of that time. I wrote a bestselling leadership book called The Making of a Manager in 2019. Currently, I am living the entrepreneurial journey with my start-up Sundial whose mission is to help companies make faster, more intelligent decisions with data.

Who am I writing for? Those of you who know me well know that secretly, all my writings are letters to myself. It’s the stuff I need to hear. But, if you are like me—someone who loves building products; someone who is a designer/engineer/pm/data scientist/researcher/analyst; someone who obsesses about working with others; someone who’d like to better understand herself—then maybe you will enjoy reading this too.

Who knows? Maybe these letters give you some things to pause and think about in your own journey.
