Yes, I have to agree, many guys are scared to approach during the day (or sober).
I try to approach 1 new girl every day in college. Often it's a 2 or 3 set, but from every now and them I do an extra set an day just because I freaking want to talk to that girl.
Sure I've had some bad reactions, they do occur. But here's the thing....If you have only talked to a girl once you can strike up another conversation when she's standing with that cute girl you'd really want to talk to. It's not just a pua thing, it's a social thing, it's making your social activities stand out in a unique positive way
Thing is though, I wanted to ask you about this, I hardly do direct approaches, which makes it that it's hard for me to close. Do you do direct approaches? Cause in your post you mentioned something about opinion openers which is as indirect as it gets
