"most teachers want to teach because they want to help growing a child/teen/adult."
Ha! I tell you. That is the story you tell a grade schooler that's on the verge of choosing astronaut as a career. Teaching is a very respected job, yes. It is looked down upon by the "lower class", sorry for insulting anyone. It's just my opinion, m'kay? Anyways, benefits? There are a heck ton of benefits. However, I'd say not to pick it unless you are certain that you can handle the responsibility. Do not pick a subject to teach on what is interesting or that you wish to learn more about. No, you pick the subject that you know 100%. A teacher much also refine his/her skills daily and know the latest discussion topic about your subject. It's not all games and fun if you really look into it. Yes, maybe teaching does look nice from behind the desk. So I ask you, are you really fit for it?
But the one who does not know and does things deserving punishment will be beaten with few blows. From everyone who has been given much, much will be demanded; and from the one who has been entrusted with much, much more will be asked.
