Hooked: How to Build Habit-Forming Products

Very fast read. Eyal opens this book with an emphasis on addictive product development - that put me on edge and caused me to read the rest of the book more critically and with a grain of salt.

After that brief intro, Hooked jumps right into the model/cycle of habit-forming products:
1. Trigger
2. Action
3. Variable Reward
4. Investment

Although not every product or feature should use this cycle, it's a solid model to apply in many cases. Something I should look for in my work - and a pattern I see in OneDrive and other products.

That said, there was little new content for me in this book. There's merit to its simplicity, but I was looking for more meat.

Even with my “low” rating, I'd recommend this to anyone working in product development.
