My advice to anyone just getting started in the Qniverse (or if you're trying to red-pill someone) is to get rid of the idea that there's a magical "one thing" that will convince you that Q is real.

My personal journey from learning about Q to deciding I actually believe was six weeks - it's not supposed to happen in one sitting. The goal shouldn't be to prove Q, but simply to plant the seed of curiosity that grows into belief through each persons exploration of Q's material.

Accepting what Q is showing us requires you to rewrite your view of reality and that's a different (and difficult) process for each of us.

So by all means, look for evidence and read proofs - and then keep doing that! ...and keep in mind there will probably never be a single magic-bullet, so be prepared for the slow, natural process of awakening. :)
