How to be an Alpha Male- Love Systems (Mr. M, Braddock, Sherriff). The concept of the Alpha Male is hugely debated, and generally any material on it is actually detrimental. That said, I think these guys absolutely NAIL IT. This audio series changed my perspective on the world more than anything I've read in the last five years. It truly opened my eyes to how ambitious I could be, in so many areas of my life. It taught me to stop seeing people as your enemies, but just as people with flaws and insecurities. Every time I listen to this I learn something new. I seriously think I will be learning from this one thing the rest of my life. If you haven't heard it yet Mark, you really should.

To Kill A Mockingbird- Harper Lee. I read a lot of books when I was young that helped build my sense of values and morality, but this would be right up there when it comes to novels that made me furious, deeply saddened, and nakedly empathetic when it comes to intolerance and prejudice. This is just one of those books that makes you passionately determined to do your part to fight discrimination in all it's forms.

This Is Water-David Foster Wallace. I read this almost three years ago now I think, but it's still life changing. It keeps you humble, conscious, compassionate, and it still breaks my heart.
