Here’s the thing about teaching people; you can’t teach them if they don’t want to learn. And most don’t want to learn.
That’s why all you can do is live your life to the best of your ability and let it shine like a beacon for others to follow. If they want to learn they’ll come to you. And when they do, that’s when you try to teach them something.
Lighthouses don’t go running all over an island looking for boats to save; they just stand there shining.
