Well, I've had a date every day for the past few days (including Christmas day!). Most of the girls were actually around my age but had a lot of things I was looking for. All of them had lived or worked abroad at some point in their lives. They are all multilingual--I am in Korea and have poor Korean so everyone is at least bilingual that I date. One that I'm seeing is so committed to her passion that she was at design school all Christmas day.
The problem is that around my age most women are at their input stage (learning, educating themselves) rather than their output stage (being productive). Someone who is productive is inspiring to me and that's what I want, so I am still trying to find more women older than me. I'm still looking and dating, and have taken some of the suggestions here.
I met one on the bus, one at my job, one through a friend, and one on the street. I'm probably going to join a 6AM yoga class near me and see if I meet anyone there--maybe someone who likes to exercise and destress before work.
Most of the activities I do (I am a "professional" Thai boxer, I suppose) have me surrounded exclusively by men. I also study philosophy and the classes are completely full of male students.
