  • "In my experience, most stuff that you start is mediocre for a really long time before it actually gets good. And you can't tell if it's going to be good until you're really late in the process. So the only thing you can do is have faith that if you do enough stuff, something will turn out great and really surprise you."

    --- Ira Glass: The Wrong Stuff

  • "A computer program is said to learn from experience E with respect to some task T and some performance measure P, if its performance on T, as measured by P, improves with experience E."
