There is always someone better than you at something.
That thing we are measuring ourselves against may not be relevant to us. That thing we are obsessing over that we know someone else is better at, that other person is obsessing over something they know someone else is better at.
Pick the thing you want to be better at than the next person and make sure you only measure yourself against that. Otherwise you will always be distracted by the fact you are at best a distant second to someone else.
