The advanced syllabus signifies a turning point in your practice, where much more of your time is committed to developing your skills.
You must train harder.
Train for longer.
Re-examine how you teach.
You must incorporate insights gleaned from scholarly inquiry.
This is not a time to rest on your laurels.
The art is not yet mastered.
And you are not yet mastered by the art.
Dig deeper, work harder... and you will find that the art is more complex and challenging than you might have expected.
