When approaching girls I often end up having the mindset that I have to prove myself to her. I think it boils down to the fact that I've already chosen to talk to her beforehand and therefore show interest, putting me in a more invested position than her from the get go.

I'm a good looking guy, 6'3", 200 lbs ripped, I attend a good university. I feel like my SMV is pretty high.

How do i change my mindset to "she is lucky that i might spend some of my time on her"?
