"I take the position that if I am firm in my convictions then nothing someone else says should rock me. If it does then I need to stop and rethink my position."
This is very true and hits on a point that I hadn't thought about - the courage of one's convictions. You really need to have that if you are going to complete a successful Master-Cleanse because most of the world is clueless when it comes to the thing. :)
