Happy 30th Birthday, Dan!!

Arielle Shipper

When you came into my life 30 years ago, I thought I was getting a sibling, which to a three-year-old meant things like sharing or possibly competition. Instead I got a brother with a fascinating array of talents who I’d call myself privileged to have found in the world as a friend. Equally adept at parsing philosophy, selling a business, facilitating marriage vows, and getting kids in line at Romp Around - these qualities make it obvious why our relationship has always been atypically close. You’re a human I’d choose, not just one I (luckily) inherited. They say siblings are our longest relationships in life, and wow do we have a lot to look forward to. Mazel tov on the first 30. I can’t wait for the next three decades. PS: Just remember, you may be taller, but I’m older!

One of your best qualities is getting at what's real. Whether it's your articles that you wrote or projects like the sunday letter one you built a while back, and now at scale at Every where people of a similar mind share how to think about things beyond the surface level and get at what matters. Things that people are curious about, but aren't always written about, because they require some study and figuring out beyond the facts. Your appetite for understanding and sharing that understanding is a gift to us all, and 30 is just the beginning of a lifetime of figuring things out and sharing that knowledge!

He is relentless in doing right by others and by himself.  He is one of my role models in self acceptance.   He reminds me every day to just go do things.

1. Grew a porn stache, despite advice to the contrary from everyone in his life.
2. Develops deep, in-person friendships with people he originally met on Twitter.
3. Reads obscure philosophy. Always in hard copy. And annotates aggressively.
4. He's spiritual without being obnoxious
5. He's vulnerable and never tries to be what he's not.
