A wise woman once said, “Wisdom comes from pain. If you’re lucky, it’s someone else’s pain.”
There’s truth to that. Everyone will have difficult experiences. A lot of them have something to teach us. What we take away from those experiences can change us. If the change is for the better, that’s wisdom.
If we pay attention to what other people are going through, we can learn from that, too.
A related thought is that experience is something you get right after you needed it.
