There are too many answers to this question to count, but I believe if you find you have a passion for teaching or helping others, then that is one main reason you should become a teacher.
By teaching you are shaping the lives of others. Some students go to school and see their educators more than they see their own parents. You as a teacher have the ability to help them learn and achieve their highest potential. You are helping them become better students and better people. You help advance their knowledge. You awaken something in the mind of your student that wasn't alive before.
If you have a passion for something, why not share it with others, whatever it is? It's no use if you can't let people know about it, share it with the world, and teach it to others.
I've always believed that helping others is greater than helping yourself. If you have the drive to do this, you should be in a profession that involves this. Teaching certainly helps a variety of people. I have always strived to be a selfless individual. There is always someone out their who could use a hand. Teaching is helping others, and seeing the results in a student you have helped and you have worked with is also an amazing experience. When you help others, you're also helping yourself in a way, and teaching can be very rewarding.
It's also an exciting career. You're always learning something new and so are the students. They're teaching you and you're teaching them. The job is never boring, that's for sure. Every day is different, and you get to move around with different subjects. Even if your job focuses on one school subject, you get to study all aspects of that subject. Every day is new and exciting. When teaching you also get to decide how you will teach. Other jobs may have a set of jobs you have to complete. With teaching you can create lesson plans and find great ways to make the students enjoy learning and actually listen.
Summer vacations are also a great bonus. :)
I added this image because it relates to what I said about helping others. This is my favorite poem, "Success" by Ralph Waldo Emerson. I particularly love the line that says "to know even one life has breathed easier because you have lived, this is to have succeeded." I believe teaching can definitely achieve this. Let me know what you guys think!
