The Design of Everyday Things

I don't care if you don't care about design or user experience (ux). Everyone designs something at some point and this book is the manual of design. Also will generally help you understand the world better.

Read it.

an essential read for anyone looking to understand user experience

The thoughts on design Don gives in this book are brilliant.

I thought this book would be more specific to product development, but often I realised that I wanted to take this thoughts in to other areas. When designing processes or just how to relate to al human culture.
