Don't be one of those people...
Listen to others who have been places you never have, and who have had much more experience and training than you do. Don't be immature and stubborn.
Believe me, you'll save yourself a lot of pain & heartache if you allow yourself to be teachable and not a know-it-all.
Oh, and btw, one or two conferences in a subject does not an expert make..just an FYI. ;)
"Brothers and sisters, I could not address you as people who live by the Spirit but as people who are still worldly—mere infants in Christ. I gave you milk, not solid food, for you were not yet ready for it. Indeed, you are still not ready. You are still worldly." ~1Corinth. 3:1-2
