Success is always described by the old as something relevant to patience. In the picture, a man sits with a dozen of clocks around him. Beside him is the subtitle saying that "success means persisting five minutes more than others". We can infer from it that the man sets these many clocks just to remind himself that he should never give up.
It is very true that success derives from persistence, for which there are several reasons. Firstly, no accomplishment can be achieved in a short time, and success asks for continuous industrious work and efforts. Secondly, when one is able to insist in stepping towards achievement, he must believe what he dedicates to. This belief is the source of persistence that paves the way to success. Thirdly, just as the saying goes, "Rome was not built in one day".
To conclude, I would like to borrow another ancient saying that "he laughs best who laughs last". Laughing symbolizes the confidence for success, and confidence always yields patience and insistence. Hence, I firmly believe that if everybody applies what the picture conveys into actual practice, they will surely reap a lot.
