It's easy to plan money carefully and life vaguely - to assume "later" exists for everything you've been meaning to do. But many experiences have a quiet expiration date, and "later" often arrives after the window has closed.
This tool - based on Bill Perkins' Die With Zero - asks for one honest pass. Take everything you've been telling yourself you'll get to "one day." Then place each thing on a decade. See which decade.
Some experiences age well. Reading. Slow travel. Quiet mornings. Time with neighbours. Some don't. Backpacking with a 25kg pack. Days with your kid before they're a teenager. Holidays your parents are still well enough to enjoy. The career second act that requires a 60-hour week to launch.
Nobody's asking you to do everything before you're 50. The idea is to stop pretending the calendar is infinite - so the things you've been putting off don't quietly land in a decade where they're no longer possible.
