Nobody really likes to be lectured a lot. And, therefore, if you want to be an effective person, what you don't do is scold the person publicly all the time.
Sometimes, you have to step outside of the person you've been and remember the person you were meant to be. The person you want to be. The person you are.
Why do so many people chose to spend their whole life destroying paths they didn't even want to follow, instead of following the one path that would lead them somewhere.
We want to be famous as a writer, as a poet, as a painter, as a politician, as a singer, or what you will. Why? Because we really don't love what we are doing. If you loved to sing, or to paint, or to write poems, if you really loved it you would not be concerned with whether you are famous or not.
