Juniors ship a weekend project. Seniors spend three days picking the right framework. The more you know, the more invisible failure modes you see. That's the paradox.
The fix isn't to unlearn. It's to timebox decisions. Give yourself 30 minutes to pick the obvious thing. If it's not obviously wrong, ship it.
What seniors forget: shipping teaches more than analysis ever will. The best seniors we know still ship weekly, and they still occasionally regret it.
Another fix: pair with a junior. They'll catch the over-engineering instinct — they haven't developed it yet.
