Inspiration isn't something you can force, and when people try to it comes off corny or cloying. But there are moments when you come across words of wisdom that stick with you for years, sometimes they even influence the entire course of your life.
In many cases, people dispensing sage words don't even realize they're doing it, and strangers in passing can feel more like gurus than people we're told to heed.
I was just at my local bashes eating lunch. There was a group of people at the table near me, all of whom were getting up there in the age department. They were just hanging out, laughing, having a good time with their friends. I wasn't really paying attention until I caught the end of a conversation where in one of the men said to rest of the group
"you can never be on top of the world if you're carrying it on your shoulders." Then he said "I'm going to tell that to my grand children so they know to dream big."
