This is my newsletter, Dear Luke. I send it out every week on Friday. It's the most personal writing I do. Each week, I write a letter (it's literally a letter; I start off writing it long-hand with a fountain pen) detailing a topic that I've been thinking about -- something that's affected me recently, and the strategies that I've found useful for addressing it. I also include links to any pieces I've published or new episodes of Cognitive Revolution. If you've enjoyed any of my work and would like to support it, I would really appreciate it if you sign up. It makes a huge difference in being able to get future writing opportunity and convincing publishers to take my work. I genuinely enjoy writing this letter, and I hope that it stands out as worthwhile among who knows whatever other junk ends up in your inbox on a daily basis.
