Hi, We’re Nils and Jonas Salzgeber 👋

Hi, we're Nils and Jonas Salzgeber, two brothers from Thun, Switzerland.

We write books and articles about Stoicism, flow, procrastination, and anything else we find interesting or helpful.

Our most recent book is called Mastering Flow. More than four years in the making, with hundreds of scholarly citations, and packed with actionable strategies to experience flow, we believe it’s the most comprehensive and practical book on flow of the 2020s.

Before that, we published The Little Book of Stoicism, which has sold well over 100,000 copies worldwide and has been translated into more than 20 languages.

The goal with NJlifehacks is to help our readers become better versions of themselves – more productive, compassionate, resilient, mindful, etc. – through ancient wisdom and modern science.

What is NJlifehacks, and Why the Name?

In one sentence: NJlifehacks is a personal growth company dedicated to helping people become better versions of themselves through ancient wisdom and modern science. We do this mainly through our blog, books, and email newsletter.

The name stems from our initials:

N --> Nils
J --> Jonas

The lifehacks part is pretty self-explanatory – it's about “hacking” our lives to be healthier, happier, more self-confident, mindful, and all that good stuff.

We started NJlifehacks back in 2016 in the hope of making a living with our passion for personal growth and self-development. While the path has been incredibly tough and involved a ton of sacrifices, struggles, and heartaches, we’re glad to have embarked on it and we’re super happy to make a living doing something we love.

The Blog

We write about Stoicism, flow, procrastination, and everything in-between. While we mainly write about those three core topics, we’ve also published articles on sleep, nutrition, positive psychology, and even spirituality – basically, anything that is somehow related to helping us become better versions of ourselves. We’ve also published a fair amount of book summaries.

The Books

We've written four New York Times bestsellers and sold a gazillion copies worldwide. *Clears throat…*

Mastering Flow is our latest book, published in October 2024. It’s divided into three parts: (1) The Basics; (2) The Benefits and Dangers; and (3) Making it Happen. As already mentioned, we believe it’s the most comprehensive and practical book on flow of the 2020s. You can learn more about it here.

The Little Book of Stoicism is our most popular and successful book yet. It dives deep into Stoic philosophy and gives practical advice on how to use its principles to gain resilience, confidence, and calmness. It has been called the “most beginner-friendly and practical” book on Stoic philosophy on the market. It has sold well in excess of 100,000 copies worldwide and has been translated into 20+ languages. You can learn more about it here.

The Happy Life Formula was our second book. It’s an expanded version of a highly popular blog post we’ve published on this blog, called How to Be Happy: 26 Strategies Backed by Research. As the title suggests, this book shows you how to create a happy life, using over thirty proven, research-backed strategies. You can grab your copy on Amazon here.

Stop Procrastinating was our first book, and provides strategies to help you beat procrastination based on Nils’ own journey from severe procrastinator to highly productive and disciplined author and online entrepreneur. It’s a nice mix of theory and practical advice, and is highly recommended for anyone struggling with taking action and following through on their intentions. You can grab your copy on Amazon here.

The Online Course

In early 2019 we launched our premium online course, called Procrastinator to Producer. As the name suggests, the course is all about helping you overcome procrastination and become a more productive, self-disciplined, and more efficient person.

Enrollment to Procrastinator to Producer is currently closed. We re-open it periodically – the best way to hear about openings is by joining our newsletter.
