Married 26 years here. The biggest mistake I see my single friends make is getting in relationships with the wrong women. Beauty probably should not be a top five criteria. I am not saying you need to date hags, but for a successful relationship personality, interests, and compatibility matters much more.
Find someone that values and prioritizes the same things you do. Someone that you can communicate with and trust.
Beauty is a depreciating asset. If the only reason you are with someone is because she is hot or good in bed, then you are in for a bad time in the long run.
