CFI question

So I have yet to start my pilot training, but I like to have a game plan ahead of time, and would like to become a commercial pilot some day. I've heard that many people become an instructor to assist them in getting the 1500 required flight hours required for your commercial pilot certificate. In looking into this, it appears that you need a commercial pilot's certificate, or an ATP which also requires a CPL. I really enjoy teaching as it always help me become particularly proficient in anything I'm learning, and is very gratifying to me. But what I've heard seems to be contradicting my research.

Any insight into this is VERY appreciated.
