UX & UI knowledge sources

I was browsing the web looking for some interesting sources to learn from about UX and UI, design trends etc. and I found out that UXPin is again even more amazing that I could ever expect 🙂

They are shering e-books here with content on mobile & web prototyping, wireframing, mockups,
usability testing, project management, design process & more.

I’m trying to reserve myself half a day a week just for learning and reading about design. It’s amazing how this profession allows you to grow and forces you to develop your skills all the time.
