Note from the author

I've started 2 non-profits that raise millions of dollars per year, ran operations at one of the most successful crypto startups, and advised hundreds of graduates from top universities on how to find a fulfilling, impactful career.

Before founding Non-trivial, I spent most of the last 5 years at 80,000 Hours, a non-profit that provides free online research and personalised career advice to talented undergraduates and young professionals.

I started out in medical school. After I discovered the ideas in this course, I realised I could have a much more scalable impact outside of seeing patients but by that point, I'd spent 7 years studying to be a doctor. I created this course so you don't have to make the same mistakes I did.

“For all aspiring do-gooders and young idealists: this is a fantastic, evidence-based course on 'how to (actually) change the world'. Some really useful stuff for teachers here as well.”
