And yet Darwin died considering his career to be a disappointment."
- Arthur Brooks, Strength to Strength
As I get older, I have an obvious interest in what success looks like as as an aging person in a society obsessed with youth. Brooks examines middle-aged and elderly satisfaction though many different lenses, and perhaps the most interesting to me was the idea of Fluid vs. Crystalized Intelligence. Put simply, Fluid Intelligence is reasoning and problem solving while Crystallized Intelligence is the combined use of past knowledge. Or as Brooks puts it: "When you are young, you have raw smarts; when you are old, you have wisdom."
Strength to Strength is essentially a survey of ideas. While not all of them resonated with me, I enjoyed the journey. The book certainly helped me (as someone who just turned 50) reframe my tendencies towards synthesis and common sense as a benefit, not a bug.
