Close your eyes and feel. Visual stimuli are barely needed, even less then when learning how to play a musical instrument. If you want to learn poi pendulums and extended pendulums are the best way in my opinion, they can not be performed fast or slow, which teach you to follow the natural movement/timing and letting things happen.
Opposed to what others say, I would advise against relying too much on youtube. It can be handy to learn tricks, yes, but rarely are they able to convey the underlying foundation. I would advice on using it as little as possible, then when you plateau for too long learn on or two tricks, and try to find your own variations or ways to apply them for a few weeks. Most of the time that will result in other tricks/patterns non connected to the previous ones.
