Welcome to Quora.Your quest should end here.
I can only add : Seeker gets the truth.
- You can seek such people or attract them.Thus to attract , you may have to demonstrate traits, which you are looking for.
- These so called mature guys are often “Detached ” and “Aloof”.They will seldom follow you or message you or pamper you.This is the difficult part.Also if they do what every one else does, they will also become same!
- You have to take subtle hints from their behavior and thus approach.
- Last point : If you will wait for them to approach,I think you will wait till infinity or may get a Intellectual play boy(They are also fun, but very difficult to contain).
