hey, it’s @claire.

i write books, invest in startups, and mother some sub-humans.

this is me, in a public bathroom, with the manuscript for my 11th book and a green juice i am about to leave, forgotten, under the passenger seat of my car for 91 days until one of the small people who came out of my uterus will, “Mamá, what is the smelling?”


in professional stuff, i was an early employee at Twitter, where Wired Magazine once called me “The Woman Who Got the Pope on Twitter” and Fast Company called me one of the 100 Most Creative People in Business. these days, i’m a startup investor & the author of 9 books that have been translated into 11 languages. my 10th book will be out in 2025!

in personal stuff, i live with a lot of children who speak a lot of nonsense and one day one of them said, after being told he had to eat his dinner: Why Did You Say that to Me?

since i have always questioned everything, it’s become an effective mantra of sorts. stranger at the cafe tells me not to eat my delicious gluten-free croissant that fell on the floor? WHY DID YOU SAY THAT ME? woman at the nail salon asks me if i’m pregnant because i’m a skinny girl wearing a tight summer dress with admittedly protruding diastesis recti? WHY DID YOU SAY THAT TO ME? bestselling book says i should get up at 5 am and exercise first thing in the morning? WHY DID YOU SAY THAT TO ME?

this Substack is a space to question it all, figure it out, and decide in the deep down knowing what the hell is what. i must warn you, it ain’t always pretty. i’ve been writing on the interwebs for 18 years, and it’s been about as glamorous as you can imagine.

currently, there are 13,000+ people on this newsletter, and most of them are truly spectacular humans. just last week, for example, i smiled wide when a longtime subscriber said, “i love your newsletter SO much, claire!”

but then someone else shouted something horrible at me in capital letters that required A LOT of essential oils to come down from.

(it’s a toss up.)

but here’s what i know: i’m so happy you’re here.

ready to stick around?

thanks! wanna upgrade for the paid goodies?

i would be remiss in reminding you that you can also upgrade to become a paid-reader-human.

if you do that, you get the following content, which will set you up to get going on this whole gentle-life-optimization-with-memes thing:

  1. subscriber-only posts.

  2. complete access to the Work by Design Summit, my online productivity conference that 20,000 peeps have attended. inside, you’ll find 50+ video interviews with experts like adam grant, donald miller, and jon acuff. much of the content comes from my own book on productivity. (according to Instagram, billionaire boss sarah blakely of Spanx has read the book thrice!)

  3. complete access to the Success Mentor Summit, my online leadership conference that interviewed 100+ experts on the topic of success. i ran this summit when my mentor, legendary management guru ken blanchard, and i launched One Minute Mentoring, our book about mentoring that has now been translated into many languages.

question it all, people.
