I'm stuck in this mentality:

Either I HAVE to fast expand, or I HAVE to all-in. There is no in-between or "normally timed expansion." I don't know how to get to that point. The only example I can think of is the cloaked banshee expand build, and that expo goes down around 8:00? I'm not sure. I can't think of any other things to do with "normal expansions." In fact, I don't know what that is. Ugh. feeling lost.
