Yeah, it's pretty hard to control electricity. I can tell you, my only working technique was when i was in the middle of a class in school. I'm 13 too so, don't laugh cause I am good at fire. That's what the technique was, a total hot flame, it kinda hurt my hand. But you don't need to feel pain. Anyways, I say just channel it to a ball in the center of your palm, and if you have to bend your fingers to the center you'll be fine.
