There is a little bit of everything here, but these are my most referred to (still) and favorite books (non Fiction) w/ links to each on Amazon:
BBQ Bible by Steven Raichlen : Amazing grilling recipes from around the world
The 4 Hour Work Week by Tim Ferriss : Shortcuts and hacks for life…lots of good stuff to think about
Man’s Search for Meaning by Viktor E. Frankl : A book that puts the meaning of life into perspective
The Art of Learning by Josh Waitzkin : What the process of learning looks like for just about anything
The 48 Laws of Power by Robert Greene : Whether you like it or not, these are the laws of power that make the world go round
If you aren’t in the mood to read an entire book, this link is great from Derek Sivers to just be able to only read the notes that he took vs. the entire book…lots of good quality stuff here including some of the ones above.
