It's possible you will be able to entice your chameleon into being friendly or that he will, in fact, decide to be friendly. But there's a fine chance that he will stay unfriendly. It's not even just a veiled thing, I don't handle my chameleons routinely and neither is a veiled. My Fischer's hates me. He seems to love his cage. I'm fine with that.
I advise you to try to get your head around the idea that your chameleon might never be your TV watching buddy. Maybe he will, but if he doesn't you should still appreciate him for the lovely animal he is.
