About RCs: looking at your hands is probably the most common one, count your fingers, they might be more or less than 10
The most effective however is probably this one: try to breath through your nose while you close it with your fingers. If you can breath it is definitely a dream.
About control, I’m sadly not very good at it either, but a tip I can give you is to “just do it”.
Want to throw a fireball from your hands? Don’t think too much about it, just throw it.
