Persuasion

The use of persuasion can be the most powerful tool there is, unfortunately I cannot harness it's power. I am absolutely the worst at persuading people to do or say what I want them to do, which gets annoying. This makes me wonder if there was a person out there who was so bad at giving people what they wanted that I could persuade them to my side successfully (most likely not). I also wonder what would be the case if I was good at persuasion. Would I just expect to get what I want all of the time? When I vissualize this I dont like what I see.
