on thinking too much

Q: Can someone think too much about ... thinking too much?

This question was inspired by a post of a friend. I think it is a marvelous question, a philosophical one, actually (I specify: applied philosophy, but IMO "philosophy" is always applications/solutions oriented).

The Question, IMO, does not assume or imply that thinking too much is a bad thing, ie it does not "judge" the act of "thinking too much".

So, how much thinking can one do re thinking too much and could that qualify as much or too much? Thinking about thinking is not un-productive or "cyclical" per se. Any activity one does (and thinking IS an activity) should be evaluated from time to time with a view to better managing one's life and time.
