Good to Great
I don't remember a lot about this book but there are things I do remember about it that I have applied in my life. In one of the chapters it talks about how great leaders focus on 1 thing and do it the best they can instead of doing multi things with ok results and diluted efforts. When ever I need to decide on what goals to take on I tried to follow this advice. It not always works but it does on the things that matter. Every tool you learn you have to not only learn the tool but also when to use it. Same thing with this book. It will teach you a great tool but you also have to learn when to apply it. Anyways this is definitely a great book to read. Not my favorite but a good book nonetheless.
