Oh the word 'efficiency.' Bane of my existence sometimes. So often we're encouraged not to linger over ideas for too, not to slow down and ruminate. Instead it's action, reaction--hurry up and complete one task so there's time to move on to something else. What else? Anything else--the new, the now, the next. 

Take your brain, fraught with all its messy smear of ideas, it's only once you let dreaming take over 
to smooth out the minute details that flimsy, fragmented concepts may enter the real world. So beware creeping efficiency because if you lose the time to dream, you will eventually lose your mind.
