Lose the necklace and beard. Button up the shirt. Maybe wear a nice plaid flannel ;-). Slow down the speech and easy on the "unnatural" speech patterns, you look and sound like you are hawking something. It also sounds like you are trying as hard to convince yourself as you are us about what you are saying....and I think it's not because what you are saying is wrong, but because you are forcing yourself to act out of your natural style.
Good info, just tone down the delivery. Be yourself.
Take care,
