1. stumble over differences from their normal approach
2. catch on and use it everywhere (Stockholm syndrome? Testing limits?)
3. finally find places it doesn't work and can apply judiciously
Given that in our profession we're constantly learning and experimenting, Uncle Bob is still doing that to this day.
