Hi Fizzy, thank you! It's good to hear that. I see now that it is the same as manifesting anything else. I am manifesting a SP too and I know it's done, and therefore neither pay attention to nor get upset at any physical 'evidence' to the contrary. Similarly, I can take for granted that I am the best in my class (or whatever else) and not be swayed by what happens around me.
I also came across this idea from an old post in another forum that no one else really has the same exact desire as we do - not in the same way we want it, for the same reasons. That also really helped dispel the idea of competition - that no one's really out there trying to take anything from me. We are all non-physical energy beings working towards our own very unique special goals.
