Is all this just validation? Am i even allowed to be a part of it?

Well as a kid i think I'm constantly looking for validation. Even on this app. I took an iq test, got 140, took a different one a week later and got 115, took another one and got 157. What the actual hell.

Maybe I'm actually stupid and these tests are tweaking and all this is my brain trying to tell me that I'm smart enough to have it all figured out.

Help?
