There are only two things in this life I know for sure: 1. That we are all related, and 2. That we should strive to be as kind as possible, under any given circumstances. That's it, that's as far as I'll go. Even something as seemingly obvious as the concept that we should work hard can be tricky; consider that we don't always really know what, exactly, we're working on or working towards, or whether it will turn out well.
