An artist's job is to make the invisible visible.
I was asked to act when I couldn't act. I was asked to sing 'Funny Face' when I couldn't sing, and dance with Fred Astaire when I couldn't dance. Do what you can't do.
Program testing can be used to show the presence of bugs, but never to show their absence!
我不想和以前一样好,我想比以前更好。
