At first blush, this is not very productive, all this quiet and thinking.
Often of late an Idea sneaks in during quiet thinking time. It's so big, so capital, this Idea, that I am tempted to stop thinking! To rush to get that little notebook and immortalize my brilliant notion (full measure of humility here) with the instant-gratification sound of chicken scratch graphite hitting composition paper.
If it's that good, it'll still be there when I'm done thinking.
I try not to overemphasize this thoughtful time by scheduling it or by calling it something grand (meditation? intimidation!). I just find it here and there, in the serendipitous moments of littles napping and biggles reading and dishes drying.
Do you afford yourself that time?
