Visualization in spell casting- How does it work?

I read all the time about how important visualization is when casting a spell. I am fairly good at visualizing and fantasizing, but that doesn’t mean what you imagine is going to come true. When I was younger I would visualize myself playing football in the NFL. Did it happen?..No. In high school, I would visualize myself making out with my favorite cheerleader. Did it happen?..No.

So what is required to make a spell effective, in addition to visualization?

You also need a “path to manifestation”. Or as some people put it “get in the corridor” where you’re in the right time and place to be in the running to recieve.

That’s not the same thing as using the magical imagination. You weren’t visualizing with energy and intention.
