Improve how quickly you recognize mistakes.

The cost of a mistake is mostly determined by how long it runs before you notice. Catching it in a day is a minor correction; catching it in a year is a rebuild. Speed of recognition is a learnable skill, and it improves outcomes more than being right more often.

Build in something that shows you reality earlier. Ask for feedback sooner, check assumptions in the first week rather than the last, and hold your conclusions loosely enough to notice when they stop fitting.
