Mark Manson would say it's about valuing your opinion of yourself over everyone else. Great. But what does it mean in terms of actions you make, and things you say?

I'm generally not needy, but when I really like a girl, I can be. I have a date later today and I don't want to be needy. What should be my mindset? How can I go in NOT thinking "man, she's hot" and treating her differently than other girls?

Yes, I know her shit stinks but I tend to be a little more supplicating with girls I like and a little less risky.

What should be our mindset before a date, to be non-needy?
