I believe that Hypnosis can greatly improve one psychokinetic abilities. Simply put yourself in trance like state and tell yourself "You are a powerful Pyro kinetic and you get more powerful at it everyday". I'm not saying you'll instantly become a powerful pyrokinetic, But if you have have any pyrokinetic abilities at the moment you should notice them becoming a lot easier to handle. Do this for about 10 minutes a day. But, Over a period of time you should start to notice your powers becoming stronger and more powerful.
