Yeah thats the thing. It's so much energy on something you may never believe even if you were told the gods honest truth at every turn.. Bottom line is more important to me personally. Plus just changing links when I think I'm not converting obviously
Hell, theres been times where I've flat out told affiliates of ours that "hey, you've sent xxxx number of hits and not a sale in so long, you should pull that link because your traffic isn't liking it at all.. try this other tour instead."
It's a money thing after all.
