Once the obstacle of a new challenge has been surmounted, your body adapts and the exercise feels to be easy.
It becomes familiar and the difficulty fades.
Care must be taken to maintain the quality of the movement.
Considerable ongoing refinement is still necessary - and always will be.
There are no plateaus.
You must continue to challenge your mind and body.
The syllabus will present countless new obstacles.
Each one will cause you to falter, re-think how you are practicing the art, and then work around the problem.
This journey will require considerable tenacity. And humility.
