Is it hard to find a girl at her early 20 but has a mature mindset like 30?

i was never mature, and ill never be : -D

not in the past, not now and not in 20 years.

the question which bothers me in this thread is rather why it needs to be a GURL in her EARLY 20s ( ͡° ͜ʖ ͡°) wait, what?!

so much about being mature, im sry xd

I doubt a whole lot of fellas/lassies at that age know what they want in life considering they barely started playing the full version of adulthood and are still testing the waters of the larger world rather than diving face first then swimming out of it in bewilderment and regret a few years later.

@ OP:
Why don't you look for a woman in her 30s then ?
Nobody will even lift an eyebrow at you for dating someone a bit older than you.
Around 30, women usually know what they like & want from life. And even non-Asian females may still look very young & desirable in their 30s. Lucky you !

Little bit of maturity and playfulness combination is the way to go.
