Building a Second Brain is much more than just another productivity method—it's a survival guide to managing the complexities of modern life.

Author of The $100 Startup and The Happiness of Pursuit

Building a Second Brain was one of my favorite books of the year. It completely reshaped how I think about information and how and why I take notes.

What if you made use of the ideas, wisdom, and resources available to you online instead of stockpiling and hoarding information with no end in sight? 

What if you knew with total confidence that you could find the information you need when you need it instead of wasting time looking for notes you swore you’d saved? 

What if you could leverage technology to think better, clear your mind, and get more done instead of letting it disrupt you with constant notifications and demands? 

All this and more is possible with a Second Brain – a trusted place outside your head where you can collect and organize your most important ideas and insights and use them to do your best work.

Praise From Smart People for Building a Second Brain

“Tiago has put a magnifying lens on the best practice of external capturing to keep our heads open for effective thinking and creativity. This is a well-written, cogent, and useful manual for staying clear in the knowledge-worker world.

David Allen

Author of Getting Things Done

A must-read for doing difficult, creative work. We all struggle with having too many ideas, but no system for taking action on them. Tiago creates a structure for staying on top of information in an age of overload.”

Scott H. Young

Author of Ultralearning

“Building a Second Brain will make you rethink your relationship with knowledge. Tiago's method offers a paradigm shift from the tiring quest for self-improvement to the freedom of self-expression. After reading the book, you will finally be able to focus on what matters: connecting ideas and generating insights.”

Anne-Laure Le Cunff

Founder of Ness Labs and Phd candidate

What Readers Are Saying

Meet the Author

Hi, I’m Tiago Forte

I’ve spent more than 10 years researching and experimenting with a new way of organizing our digital lives and improving our productivity using technology.

What started as a quest to deal with a chronic illness eventually turned into a life-long mission to help you harness the full potential of your ideas and turn them into reality. I firmly believe this is a crucial part of creating a better future for all of us.

Over the years, I’ve taught thousands of people around the world how to clear the mental clutter, organize their knowledge, and capitalize on the full potential of their thinking through my popular online course Building a Second Brain.

Teaching my methodology live in 16 cohorts with over 6,000 students allowed me to rapidly improve every part of it and make sure it works for a wide range of people.

Now, you can access the Building a Second Brain system in its most succinct and distilled form: a bestselling book available everywhere books are sold.

I can’t wait to share it with you!

Based on Tiago’s work with the following organizations and over 25,000 online learners

“Tiago is a master organizer. His book, Building a Second Brain, is the ultimate guide for anybody who wants to succeed in the Internet age. It’s the single best system I can recommend to any writer. You’ll leave feeling calmer, more creative, and much more productive.”

David Perell

Founder of Write of Passage

“Reading this book feels like being let in on a secret. Tiago offers powerful, elegant, and deeply human solutions to some of the most stubborn challenges we face trying to make sense of the digital age. An absolute must read for anyone interested in personal knowledge management.”

Ryder Caroll

Author of The Bullet Journal Method

“Getting more out of our digital tools is something we should all care about. Tiago offers an excellent guide – this book will help anyone organize information in more useful ways, and ultimately do better work.

Who Should Read Building a Second Brain?

The answer is: Anyone who wants to succeed in our modern, hyper-connected world.

Our digital lives are expanding exponentially. Your profession and even your side projects and hobbies require you to consume and understand more information than ever. 

The bad news is: It’s only going to get more demanding. 

The most important factors for success are no longer how many hours you work, how much effort you exert, or where you are located. What matters now is what you know, how well you document and organize that knowledge, and your ability to share it with others.

The good news is: You can leverage technology to capitalize on the full value of your ideas and knowledge

Personal Knowledge Management has become an essential survival skill for everyone navigating the modern world.

You can’t afford to burden your biological brain with trivial details that don’t ultimately give you the life you want. It’s time to build a Second Brain and take hold of the potential you know you are capable of.

“The passion economy is one of the next great waves of entrepreneurship in the world, and the ability to cultivate and leverage your personal knowledge is key to being part of it. Tiago’s book is an excellent introduction to how to succeed in the new landscape of creativity online.”

Li Jin

Co-Founder and General Partner at Variant

"Tiago's changed the game with this book. Building a Second Brain completely changed my life and the book is a great distillation of the key ideas."

Ali Abdaal

YouTuber and Entrepreneur

“Relying on your brain alone will be a thing of the past! Tiago presents a new way of thinking in this new age productivity classic.”
