People usually want a career that they enjoy and are capable of. They also want a career that they both admire and respect. To be a good teacher one must be patient, determined, and devoted. There is a level of resistance in every classroom. Teachers cannot become frustrated with a student who seems to oppose learning.
Every student learns best in a different way.
The job of the teacher is often to both discover these different teaching techniques and utilize them in the classroom. There will always be lessons that are harder to teach and harder to understand. A teacher must have patience to explain things repeatedly, and also have the creativity and knowledge to teach it in several different ways. A teacher must be determined. A class would learn very little if the teacher had not motivation.
