The Woman-Part will come by itself.
I mean that makes it sound like you should just wait around for a partner to fall into your lap. You shouldn’t.
The good part of your advice is yes, invest in yourself and your own hobbies, interests, career, finances. That will absolutely make dating easier.
But don’t just sit there doing nothing thinking because that stuff is squared away someone will come knocking. That’s not likely to happen unless you’re just too handsome to function.
But if you’re out in the world involved in things you’re interested in, it will happen more naturally.
