"don't listen to this MESS on this Forum!"

If that's what you think of this place, feel free to not post here.

N6724G. ATP will not make you a great CFI. No place can. I actually recommend ATP for the CFI's as they do a lot of them and know how to get people through it. But, you need to have your act together before you go and have a good background before you get there.

You can't really be "taught" how to be a good CFI. I think all the CFI schools put out a minimum standards product (except for maybe FSA). That's no big deal as long as you don't turn around and jump into teaching guys who are gonna be airline pilots in six months. But, if you get the certificate, and kinda ease into instructing, especially with some high time mentors to help you, you'll be fine.

The only way to be a great CFI is to do a lot of it and gain experience.

You were lucky to learn, so far, from high time CFI's. You got that going for ya. What youth aviation stuff are you doin?
