Yes, day game is the best in my opinion. Basically, you learn to
never let an opportunity go to waste. Commuting to work? Out to lunch with coworkers? At a bookstore or coffee shop? Buying a present for your folks? Heck, even running in the park?

If you see a beautiful women, you approach, or you keep hating yourself over not approaching until you do.
However, I think bars/clubs are definitely doable, but in my opinion, it also depends on location. If you live in Cali, NY, or a place similar, clubs/bars are fine, and there's a trend of PUAs using it as a place to sharpen their teeth (and based on others' results, I think that it will do that more so than day game, but I just don't like it). Where I live, women are either too young, too old, or not my kind of girls (but I have met cool girls too and don't mean to stereotype bars/clubs here), just try it in your area. You don't have to drink or "party" actually; most people just assume that you've been drinking even if you haven't, or if you get a water, it looks similar to vodka.
I find that people generally do one of these (if we're excluding parties/bars/clubs) after college:
- Online dating
- Church (singles night)
- Coworker
- Social circle
People can also meet at some event (concert, art show, etc.), but I don't list it above because it requires being more over Approach Anxiety than those items; therefore, I'd compare it with day game. A "coworker" also toes the lines because it has complications, but I've known plenty of guys to date women at work who have never cold approached a woman.
These are fine ways to meet women... but it is very limiting. Instead, it's best to iron home the idea that you should never let an opportunity pass you by -- day or night. If you see a woman that catches your eye, you approach.
As far as that list, I still haven't truly tried online dating (but I have met women in chatrooms), and I don't go to church. I did have a coworker set me up on a date with one of her friends. If you're generally friendly with people at work, this happens. But, I went on the date, and it was horrible. I would rather get rejected than go on a date with such a girl again. We had nothing in common, and she was very... hypocritical towards me in conversation.
