Plan B

“Plan B” recurs in Kyle’s notes as a backup-plan discipline, and two books develop it from opposite ends. In The Start-Up of You it is a career construct: the highlights warn that throwing your whole identity into one thing leaves you “vulnerable to an identity crisis when you pivot to a Plan B,” and argue for building up soft assets so that when an inflection point comes you can “swiftly parlay skills into a Plan B.” The book’s two rules of thumb are that the best Plan B is “different but very much related to what you’re already doing,” and that — unless immediate action is forced — you should “start your potential Plan B on the side” rather than abandon Plan A first.

In The Self-Driven Child the same phrase names a stress-regulation tool. “Plan B thinking” (“What are some other things you could do if it doesn’t work out as you hope?”) is presented as key to handling setbacks: by envisioning alternate futures and backup plans, kids and parents learn that if Plan A fails “the world won’t come to an end.” The book frames it neurologically — Plan B thinking “strengthens the prefrontal cortex’s ability to regulate the amygdala,” counters catastrophizing, and increases flexibility and adaptability. It surfaces in the book’s modeling of choices with children (think through pros, cons, and a Plan B before deciding) — the passage where Kyle’s note connects the visualization habit to Chris Hadfield as a model of deliberate mental preparation under high-stakes uncertainty.

Where this appears

• The Start-Up of You — Plan B as a career-pivot framework: related-but-different, started on the side, built on soft assets parlayed at an inflection point.
• The Self-Driven Child — “Plan B thinking” as a stress-regulation and anti-catastrophizing tool that strengthens prefrontal regulation of the amygdala.
• Chris Hadfield — invoked via Kyle’s note on the Self-Driven Child passage as the model of visualization and deliberate preparation that Plan B thinking embodies.
