This line...
(Actually, I'm not really sure if it's only a line, or much more than a line - although, if you extrapolate and say that yes, it is much more than a line, then I guess this line could be a philosophy or maybe even a way of life.)
... occurred to me yesterday:
Life is too short for answers, we have time for questions only.
And if this pithy (or badly constructed) little line is true, (whatever that means!) then the quality of a life rests on the quality of the questions with which one wrestles.
A thin reed on which to base a life, but I suppose it could be just enough.
