If you are interested in user interface design and think all books are TL;DR, here you go.
But in all seriousness, there are some small nuggets of information in there for anybody who wants to get into UI design. #18 is my favorite:
A curious property of great design is that it usually goes unnoticed by the people who use it. One reason for this is that if the design is successful the user can focus on their own goals and not the interface…when they complete their goal they are satisfied and do not need to reflect on the situation. As a designer this can be tough…as we receive less adulation when our designs are good. But great designers are content with a well-used design…and know that happy users are often silent.
