Love the format, brief snippets, two to three pages per topic that can be read in a single sitting. It offers some nice insights, and doesn't feel too much like a blog. I adopted the phrase "will it matter a year from now" and this has made a huge difference in my life.
My only beef is that the author obviously has a pretty good life, that he seems to assume it is typical. Not trying to make direct comparisons or do "as ifs", but for someone for example going through difficult times, for example divorce, child custody issues etc, some of the advice about family life could be more of a kick in the guts. Carlson wants us to think this is just "small stuff" ... yes I get it, don't sweat it ... but a little more empathy for those with the "big stuff" wouldn't go astray ... this is what we look for in a self help book like this.
Overall though, I'm happy to have read it, and feeling more positive about what is ahead.
