Then I checked out Simplify Your Christmas by Elaine St. James. She has some other books on simplifying life so I already knew she had an edge. She included interesting traditions (even around Winter) so I enjoyed it. It was also a short read.
I've seen some hype about the Bulletproof Executive (Dave Asprey) so I read his book called The Bulletproof Diet. It's very interesting in that it comes from the biohacking world. He spent a lot of his own money applying research, trying things out etc. and losing a lot of weight in the process. He's a Silicon Valley guy, and I think his perspective is worth a look. I think I might try his 14 day process approach soon just to see if it agrees with my body and really does jump start brain power and loose extra pounds. (I've gained a few so I guess that'll be good timing?)
