Your original post did not say whether or not you have any experience teaching. If I were you, I would try to find some experiences teaching to see how you like it. For example, volunteer to work with students who come to your floor ... offer to orient them to your unit ... work with new employees ... etc.
Some people think they will like teaching because they imagine only the positive aspects of the role. Then hate it once they face the day-to-day realities of it. Others try it and love it.
Also, you might want to talk with people in your area who are knowledgable about the job market in your town. While there is a national shortage of instructors, the situation might not be what you would prefer in your particular geographic region. You might not have as many choices as you would like ... or the salary might not be as good as you expect, etc. There are reasons for the national shortage of nursing instructors. Be sure you know what you are getting into.
Finally ... be sure to examine all types of teaching. When you think "teaching" a lot of people immediately think of teaching beginner-level students, working for a nursing school
. However, there are also career opportunities in staff development in whiich you teach existing nurses ... and in public health education. There are lots of places and people to teach.
