Cooperation works better than constant conflict because nobody is right all the time, and a broken clock is right twice a day.

Nobody is right all the time and a broken clock is right twice a day.

When times are tough, constant conflict may be good politics but in the real world, cooperation works better. After all, nobody's right all the time, and a broken clock is right twice a day.

Even a broken clock is right twice a day.

Even a stopped clock is right twice a day.

As the saying goes, even a broken clock is right twice a day; that doesn't mean you should run out and buy one.
