"Success" might not be the goal here perhaps, because there might never be a good enough point ,it just keeps going. But I do think that having something to work toward, a purpose of some kind brings life value beyond the result.
I have known people previously who have left relationships because their ex partners were "too ambitious" and so hyperfocused on achieving whatever it was they wanted to achieve that they neglected the relationship
This is addiction, isn't it? It is a bit different than what I mean by ambition, because I don't see single-mindedness as an attractive trait. But, there is something about a person that goes a little extra, finds a few minutes more to work toward something they are after that is attractive.
And in one case the person in question wanted to be the absolute most important thing in their partner's lives bar nothing and refused to "compete" with a dream.
Some call it love - I might call it a toxic relationship! :D
I didn’t have a word for it at the time but now that you mention it… 😱🤣
