Most normal that I see that have the most success in dating don't do cold-approach.
They use the friends they already have (could be a group of just all men even) to meet an endless amount of mutual friends.
How?
The closest thing they will do to cold approach is go out to a bar with their buddy's and start talking to another group of friends stood next to them in the smoking area.
Talking to the person that happens to be next to ya when your already talking with your friends isn't cold approach.
