The sign of a true learner is not just the knowledge he or she has accumulated, but also the ideas that have been jettisoned. (Neil Cole, author)

When the light goes on in your brain, giving you a new idea, what do you do with it? Are all ideas good ones? Should we pursue every scheme that comes to mind? The obvious answer is no, not every idea is a good one. So a wise person will evaluate the brainchild, follow the good ones with determination, but forget those that don’t hold promise for good results.

I will reject perverse ideas and stay away from every evil. (Psalm 101:4)
