This is the type of person I am drawn to; conservative dress, almost business-like.
I was in Cabo on a business trip and all the guys were going after these wild-looking women like you describe as your friend. I spotted this girl hanging with her friends who looked almost out of place in the dance club. I was drawn to her like a bee to honey. I asked her to dance and found out she was from NY State and on a girl's trip. We played cat and mouse for a little while then eventually connected and ended up dating for a few months.
For me, putting in the effort is worth the work to achieve a higher quality individual.
I eventually got married to a beautiful woman. We have been married for eight years and it's been great. She told me that she had to do a lot of work when we were dating but it was worth it. It's not something that people often think about, but it should be a reflection of your value as an individual.
