Have you read the Let Them Theory? Why is it that her choices wind you up so much? I think you're letting her life choices get to you more than they get to her.
She's getting 7-8 hours sleep, which is decent. She's got a full time job, which is normal and positive.
Do you care because you think she's got so much more to offer the world? Or because she used to have hobbies and interests but now she doesn't and you're worried she's depressed?
Do you think that you are a better person because you get up early and because you go to the gym?
Not everyone enjoys the gym.
Waking up earlier does not make someone a better human being.
I am saying this as someone who gets up early, goes to the gym, has a full time job, volunteers, sings in a choir, walks my dogs, raises my kids and so on and on and on. None of that makes me a better person than a friend who chooses to live a different lifestyle or needs more rest. I'm a busy person and I love having a full life but I have friends who prefer a slower, calmer, simpler life and that's absolutely fine.
I have worried for friends in the past whose worlds seemed to have got smaller. e.g. one who went from having a cool busy full on job, travelling, playing in a band, running marathons and then after a break up and a terrible relationship they ended up with none of those things, living with her mum.
But the lack of sports and hobbies was the symptom of the control the partner had on her, it wasn't a choice. He'd ruined her confidence and finances so she couldn't travel. He'd cut her off from her band mates and colleagues. And so on.
Finally, are you actually good friends or is this just someone the same age who's been in your life from school?
