Time
The one who does the work does the learning. So: do less; teach more.
Some strategies:
Lesson Planning
Rather than scripting the entire lesson, build in flexibility.
Set boundaries to prevent over-planning.
Feedback
Consider asking students to pose two questions along with large assignment submissions in order to guide your feedback.
Based on the flow of the course, decide just how detailed the feedback for each assignment needs to be.
Consider using a rubric to structure your comments.
In writing intensive courses, set aside time in discussion section for students to read your feedback, and ask them to identify next steps. This way, you will avoid providing identical feedback multiple times.
Utilize peer feedback.
Consider asking students to occasionally mark their own work.
Student Communication
Set boundaries around when you will respond to student emails, and communicate them clearly to your students.
Consider not sharing your cell number with your students; as Cat Saint Croix says, there are never any philosophical emergencies.
