We make a ton of calls everyday. Here's what I do. I know I'm going to make one-hundred calls whether I want to or not. So I just get through it as quick as I can. If people don't answer that's okay. One less call to make. If people are rude and hang up. That's okay. One less call to make. Before I know it, my calls are done and I've made a few appointments.
But hey, that's just me.
