The simple solution is not to look on Instagram (which is a bit trite).
The more complex solution is to develop a worldview where you only compete against yourself, i.e. is what I'm doing now going to make me a better person in X time.
It's up to each person to decide for themselves what better means, it could be an emotional thing "will it make me more empathetic?" or a financial thing "will this allow me to earn more money?" or something else "will it make me a better programmer, chess player, cyclist, *happier*?".
For all the size of the world and its complexity it collapses down to a local optimisation problem for you as a person.
