Pain is temporary. It may last a minute, or an hour, or a day, or a year, but eventually it will subside and something else will take its place. If I quit, however, it lasts forever.

——辛格1978年诺贝尔文学奖获奖演说

The first erroneous assumption is that quality means goodness, or luxury, or shininess, or weight. Quality means conformance to requirements.

天赋是上帝赐予的，要谦卑；名声是别人给的，要感恩；自负是自己给的，要小心。
