What does it mean that integration across time?

Connect what you know now with what you knew before — your past schemas contain wisdom.

Example: At 25 you believed 'move fast and break things' was the only way to build products. At 35, after cleaning up the wreckage of three teams burned out by that philosophy, you believed 'move deliberately and build sustainably.' Both schemas were rational responses to their contexts. The 25-year-old was right that speed creates learning opportunities. The 35-year-old was right that speed without recovery destroys capacity. Integrating across time means holding both versions in view simultaneously — not choosing one, but extracting the valid kernel from each and composing them into a schema that neither version could have produced alone: 'move fast on what is reversible, move deliberately on what is not.'

Try this: Draw a vertical timeline. Place five years at the top and today at the bottom. Pick one domain — career, relationships, learning, health, or craft. At each major inflection point on the timeline, write the core belief you held about that domain at that time. For each version, note what was right about it and what was limited. Then write a single sentence that integrates the valid elements from all versions into your current understanding. This sentence is not your final answer — it is your temporal integration draft, and it will itself be versioned.
