I know you've heard it said before: Practice, Practice, Practice.
Perhaps you can find a local class on FMQ-ing. After all, we all have different learning styles. In a class the instructor can see what you are doing and help you where you need it. Videos and YouTube are great but sometimes the 'hands on' environment is best.
Please check your LQS"s for such a class. Or if need be ... take a road trip to where such a class is offered.
happy Quilting,
