… If we have a problem and we need to solve it, until we do, we feel (inside us) a kind of internal agitation, a tension, or an uncertainty that makes us just plain uncomfortable. And we want to get rid of that discomfort. So, in order to do so, we take a decision. Not because we’re sure it’s the best decision, but because taking it will make us feel better.
Well, the most creative people have learned to tolerate that discomfort for much longer. And so, just because they put in more pondering time, their solutions are more creative.
