By this, I don't mean you will attract people with the same personality or looks.
I mean the level of evolved you are. The real work you've done (or not done).
The lessons you've learned. The behaviors you have. Cumulatively.
If you keep attracting a certain type of person, and particularly a type you don't want to be with, the best way to stop that is self-work.
Similarly, if someone seems way too perfect, and you know you aren't your best self yet, there might be a red flag you can't see on the surface.
Self-examination (no pun intended) can help with all of the above.
