If there's one thing I've learned, it's this: We all want everything to be okay. We don't even wish so much for fantastic or marvelous or outstanding. We will happily settle for okay, because most of the time, okay is enough.

This quote suggests that in general, people aren’t looking for extraordinary things in life. Instead, they just desire that everything is going alright. People don’t expect to have amazing results, but they would be content if everything is in order. In other words, “okay” is a good enough result for most people, and they are happy with it.
