Hey Vincent,
I can't really tell you anything you probably haven't already heard, but I'll do my best to explain my thoughts on that subject.
First of all, photoreading stimulates the areas of the brain which use intuition, yes? So I would say photoreading and activating as many things as you can will definitely strengthen your intuition, thus leading to more spontaneous activation, or at least your first one, if you haven't had it already. Photoreading anything you can get your hands on, even if it's just a few pages. That's what I'm beginning to do, and photoreading is becoming more and more easy for me, and that gelling sensation is occurring much, much more often.
Another piece of advice that I might be able to give you is to use the theory that Paul explains in the course. That is: Want it to happen, Expect it to happen, Get out of the way and LET it happen.
Make a request that your brain search for the answer, then immediately start focusing on something else. Then begin noticing any thoughts that you might have, and if they seem related, they're probably the answer you're looking for.
I know it might seem like something really cool to experience, but it's not 100% necessary, so don't force it upon yourself. Simply expect it to happen, and keep using the photoreading process every day. If you dedicate yourself, you will achieve what you want. I can almost guarantee it.
