I love doing these book lists because it gives me a clear idea of where I have spent my mental energy in the last four months. This time, I can see that I've spent a LOT of time reading self-improvement books around creativity, collaboration, and productivity. I wonder if I have anything to show for it... I've also noticed that the lists are getting longer and longer. I'm not sure if that's because I'm reading more or if it's that I'm more careful about choosing good books (and finishing them!) because I know I'll be writing about them later. Either way, here is a good long list of what I have been enjoying over the last four months.
