Is There Anything That You Shouldn't Skip Into in Cold Calling?

I've been doing it 10 years and I still don't get excited. So, for me I still ask permission because that's just like maybe it's a cultural thing. You can send out an unconscious vibe just from your tone,. Just from your demeanor. If you're smiling versus like sitting down hunched over. That actually changes how your voice sounds. controlling your voice matters 100%. It's like psychology. It's not even. I'm not saying like pseudoscience here. Is there anything that we should take in consideration there in the first five seconds? Let me know if I'm skipping ahead.
