People who are truly successful don’t worry about what other people are doing.

If someone does nothing but complain about other people it’s a big tell on how successful or unsuccessful they are themselves.

Also most successful people don’t constantly brag about how great they are.

Success is it’s own reward & is independent of other people. If someone is constantly screaming about how great they are & how everyone else is a loser thats another big tell on how successful or not that person actually is, not to mention their happiness level,
