Having a quiet mind; being internally focused; thinking slightly positive; not thinking about the problem directly

Being internally focused - Do less of: Telling others your ideas; Pressuring for results. Do more of: Asking for the ideas of others first; Allow space for reflection.
Thinking slightly positive - Do less of: Asking Why questions; Criticizing or dismissing. Do more of: Asking how questions; Being non-judgmental and more encouraging.
Not thinking about the problem directly - Do less of: Focusing hard on the problem; Asking about what has been done so far. Do more of: Focusing lightly on possible solutions; Considering options for moving forward.
