This is an excellent question, one that many teachers face. Maintaining our personal practice is a big challenge, especially as our popularity grows and more demands are made on our time. I suggest scheduling time every day for your personal practice. It’s best if it can be the same time each day. This is your time for your growth, your healing, and your exploration. If during this practice you come up with some wonderful, cool insight for your students, great. Write it down. But then come back to your own practice.
When I ‘m teaching a workshop, my morning practice includes the session that I’ll be teaching that day. I do this to “test-drive” the classto make sure its sequencing works smoothly and the poses are compelling for the level of students enrolled. If I have time, I also do a separate practice, one that’s my personal practice. If I don’t have the time for that, then I schedule an extra-long practice, say three hours, part of which time is for the class I am about to teach and part of which is for poses I need or want to work on.
To answer your question, make your practice very personal and also record the insights you feel will be wonderful teaching gifts. If you are going to teach a workshop or class, do that class privately before teaching it to be sure that it works. But know that if you are always practicing the class you are teaching your students, then you are not practicing at your level. You are ripping yourself off. You need to practice at a level that draws you deeper and feeds you with challenge and inspiration. Therefore, be sure to include time for your own practice.
