I highly recommend subscribing to The Orbital Index newsletter. One of the 3 newsletters that I actually read every week. It's (almost) completely outside my profession but very interesting to read nonetheless.
2. James Clear's (https://jamesclear.com/newsletter), author of the Atomic Habits, which is a fantastic book about... habits (https://jamesclear.com/atomic-habits)
Both are no-bullshit and consistently provide value.
