Many scientists move on from a problem as soon as it gets too hard to make further progress. Those who are very creative open up entirely new areas, but others just follow one fashionable area after another. If everyone did this, our understanding of phenomena would be quite superficial, but fortunately there are other scientists who stick with a problem, no matter how old and difficult it is, to get right to the bottom of things. - Venkatraman Ramakrishnan
