If you do something wrong, they talk about you. If you do something right, they talk about you. If you don’t do anything, they are still going to talk about you. What I’m you supposed to do then?
Well, people are going to talk no matter what and are going to give advice to you no matter what. Ignoring them is the best way to handle any situation. Do what will make the child in you proud of what you are today. Do what makes you wake up in the morning without an alarm and do that thing with all your heart. That matters, not what the people talk about.
