I have to balance this by saying that some of the most satisfying and elegant solutions I have found came from a careful, organised, timely approach to the problem where many options are considered, rather than slapping something together in desperation. It's possible to work very quickly under these conditions - and much more pleasant than "crunch time". I get high-pressure inspiration too though...
