When you want to become a yoga instructor, you are going to have to make sure you fulfill any requirements that the place where you want to teach requests. This means that you will need to have the endurance to get through the courses, and you will also have to find courses that match up with your own time schedule. One additional point to make: Each facility is unique and may require different teachers for different classes. If you are a Restorative teacher, don't expect to get an audition for the Power Yoga teaching position. If you are an RYT, don't expect the local Bikram yoga school to open the doors to you, unless you were trained by Bikram Choudhury. One key doesn't open all the doors and neither does one certification.
