what makes you, as a Q believer, so sure in the plan?

I'm a mathematician (high-dimensional statistics). Began with, oh damn those are at least some nice coincidences. Perhaps somebody spent a long time studying conspiracies, human psychology, and posted enough to make "some shit stick".

At this point I have zero doubt that Trump is connected to Q, that Q/Q+ have access to highly classified intel and that the plan is real.

There is still the off-chance that something may go wrong, because ultimately God is king and his will invariably comes. If we're too stupid, arrogant and selfish then he may just undo the plan to teach us a painful lesson. But so far there is no indication that this will be the case.

I know for fact that God is real and never had a thing for faith because I require proof to accept something as truth.

I know Q is the real deal, and for the first time in my life I have unshakeable faith that it will also succeed.

Everything right now indicates that in due time it will be Q-ed.
