This is my personal list of books I've read and found interesting. I mostly read on productivity, psychology or design. I re-designed the book covers but included a link to Amazon, so you can find it quickly!
The basics of everyday typography explained on examples. In my opinion, everyone working with any kind of graphic program or just a text editor should read this. There is way too much bad typography out there!
The classic by Don Norman, a must-read for every interaction designer! The book might seem a bit too old, but all of the principles still apply, no matter if you are a product or digital designer. Easy and fun to read.
This is the bible of interaction design by Alan Copper - the father of Visual Basic and the inventor of personas. I haven't read it whole yet (it's fairly extensive), but it's worth ever just for the personas-chapter!
Getting Things Done (GTD) is very popular time management method, proposed by David Allen. No matter if you are a top-manager or just a lazy student, GTD can be applied and hacked for every purpose! I use it myself.
