Cal does make it clear from the beginning who the book would benefit most and as a 9-5 office worker with little control over any aspects of my work, I read on anyway.

With most self-improvement books, I like to take what works and leave the rest.
I did find the pull vs push method really interesting and have researched this more to see if I have any hope to bring this to my work day.

Maybe one day I'll be in a positioned with more control and freedom and I'll remember what I've read from Slow Productivity.
