When at Webstock (holy f---, once again, an amazing conference) this year, Liz Danzico gave a great talk about giving up, quitting, and how, "... sometimes, the middle is the end" in projects. The talk was engaging and struck close to my heart in many ways. One of the many books she referenced and drew from was The Antidote: Happiness for People Who Can't Stand Positive Thinking (affiliate link). With a title like that, heck yes, I bought a copy before the conference was over.
The book has 9 sections, ranging from the cult of positive thinking to stoicism to embracing insecurity to the folly of focusing on goals to accepting death as a way of life to negative capability. Each section / chapter has a central theme, some story or author adventure, and a suggestion on how this different way of not-embracing positive thinking has helped others and can help the reader in leading a better life (for their definition of better).
Having read a number of studies about how positive thinking doesn't really work in many cases, as it's essentially sticking your head in the sand about reality, and that visualizing achieving your goals causes your brain to reward you for already having achieved them reducing your desire to continue to pursue them, I was eager to read this book.
It did not disappoint.
