Stop going to bars, you're not ready. You don't need a wing man, you're not some college kid or a 35 year old IT worker. You're a lawyer, you're smart, you're nice/mannered, you're well versed in Japanese culture. You're a god damn renaissance man, b.
You aren't going to die alone. Eventually you'll find someone you like and you'll settle down. No point in worrying about the end game right now, dude. Go have fun and realize if you strike out it doesn't go on your criminal record or some shit (well assuming you aren't sexually assaulting chicks). You just move on. As I said in the other thread, go talk to some women. Regular convos. Hang out at book stores, just reading/drinking coffee. Your personality type clashes too much with the bar scene imo, there's no point in forcing the issue just to check off some "how to score ladies" list.
