You’ll stop envying people the moment you know what you want to do in life. You can’t compare yourself to your friend who is in med school when you aim to have a degree in education; you can’t compare yourself to your businessman brother when your goal is to be a writer.
The moment you realize your goal is the moment you’ll start comparing yourself to your older self.
You’ll see that you and your friends have different paths to take and a life to live.
