I don't believe in pessimism. If something doesn't come up the way you want, forge ahead. If you think it's going to rain, it will.

The best way to measure how much you've grown isn't by inches or the number of laps you can now run around the track, or even your grade point average - though those things are important, to be sure.It's what you've done with your time, how you've chosen to spend your days, and whom you've touched this year. That, to me, is the greatest measure of success.

Programmers are not to be measured by their ingenuity and their logic but by the completeness of their case analysis.

0 is not about technology replacing humans, but technology empowering humans.

生活中唯一的限制是你自己设定的。
