One of the most daunting but beautiful facts of life is that no matter how long we live, we'll never run out of new things to learn about the world around us.
Part of this has to do with the fact that it's still so full of mysteries we have yet to discover, but also because both the world itself and the people who live in it are always changing. And those changes tend to not only teach us about the world to come, but also about what was already happening.
And, while what we learn about the realities of the world can be harsh and unpleasant at times, much of it is fascinating in a more satisfying way.
