Creative people have imagination. It’s what helps them see in fresh ways and come up with things the world hasn’t had before: solving a problem, or make something happen, or just because.
They are always wishing they were doing something else. Their imagination is working all the time whether they like it or not: conjuring something else – maybe better, maybe just different. So they either get unhappy because they are not doing it, or they off and do it and enter the next exciting cycle of discovery and imaging the next new thing.
So it goes.
That is the curse and the blessing of imagination.
