How can you give anyone your advice....really?!??!

Has anyone else got to the point in their life where they realized that everyone that has something to say or an input on what you do and how you maneuver really has no business saying anything to anybody?

What is even more crazy is when you analyze how you been moving without their input and you have succeeded way further than them in life but that always want to say something to you.

I am starting to genuinely dislike people and their conversation.
