How do you train your mind to not seek female validation?

I feel like all my life growing up, my brain has been centered around girls, getting them, impressing them, etc. I feel this stems from seeing that guys who get the pretty girls are at the top of the food chain in life. I’m in my late 20’s now, married, and i still find this feeling lingering. Like if I have a new female coworker, I feel the need to get her approval. How do I grow out of this mindset?
