Every choice you make today is tomorrow’s history. Make history you won’t need to explain.

Decisions stop being flexible the moment they are made, and they join a record that other people eventually read without any of the context. Most regret is not about dramatic mistakes, it is about small choices made for convenience that turned out to be awkward to account for. The test is whether your reasoning survives being described plainly.

Before the next borderline decision, imagine explaining it simply to somebody you respect. If the explanation needs work, that is the signal. The version needing no defence costs a little now and saves a great deal later.
