I think a close cousin of being “addicted to success” is being addicted to relevance. It’s a problem.
“It is often believed that President Teddy Roosevelt called social comparison the ‘thief of joy.’ Whether he said it or not, it’s true: researchers have long found that social comparison lowers our happiness. But you hardly need a study to tell you that — just spend a few hours browsing (social media) and see how bad you feel about yourself. this is because you are comparing your success with your perception of others’ success, as depicted in information of dubious accuracy. Nothing good comes of this.” Arthur Brooks, From Strength to Strength
