I know the feeling.
When you watch someone else, it looks like they are working with clay the consistency of thick yogurt. When you try it, the clay feels like almost set concrete.
Follow the advice above and just keep trying. It took me about two years (intermittently at evening classes) to get the clay to centre and cone up and down. It's just a case of getting in the zone, try it with your eyes closed, and pushing the clay with your mind as much as with your body. It's a whole body workout, not your fingers, not your hands, not your arms, not your shoulders, not your back or your stomach, but all of them working together.
Experts make everything look easy, the rest of us have to practice, practice and then practice some more.
Yes to all this.
