If you want to go further, books are the number one place to start – next to talking to experts. With no other method you’ll find information as dense as in books.
Here are my favorites, grouped by topic:
Productivity
Getting Things Done by David Allen – Almost needs no introduction, as David Allen laid the foundation of how to effectively make use of an ‘external brain’.
Deep Work by Cal Newport – This book is about realizing that we need to learn how to do actual work. Deep work. This is a skill. If you manage to cultivate and train this skill, you’ll be able to do a massive amount of meaningful work.
Start with why by Simon Sinek – Almost everything gets better when we spend more time on figuring out what the deeper reason is for doing it. Discovering the ‘why’.
So Good They Can’t Ignore You by Cal Newport – Refreshing take on the whole purpose discussion: Newport argues that we should actually focus on what we’re good at, not necessarily on our passions.
The Second Mountain by David Brooks – Whenever people have questions around meaning, motivation and life choices, I’m recommending this book.
Management
High Output Management by Andrew Grove – A classic guide that talks about the basics of managing output, and coaching you through principles any manager needs.
The Making of a Manager – A well-written and fresh guide that will speak to any new manager. Lots of concrete guidance and practical tips.
Principles by Ray Dalio – An inspiring set of principles that can be used to make any team make better decisions. Sidenote: it does contain some strategies that could be backed by more research and data.
High Growth Handbook by Elad Gil – If you work in a fast growing organization, this book contains highly specific guides. Think about things like hiring a C-level person, product management and making use of a board. Super practical and highly recommended.
