Conservatives tend to have more ambitious goals than becoming school teachers.
I can't think of one thing more ambitious than to teach--except parenthood.
Nothing wrong with being ambitious, but someone has to do the hard jobs, too.
This is the type of attitude that leads to entire generations of kids thinking conservatives are bad since there is nobody in the education system to show them that is not true.
I originally wanted to do something you would consider more "ambitious." Be a scientist, judge, or doctor. But, when I had a teacher turn my life around because of how she inspired me, I saw the impact a teacher can have.
They are just as important as that doctor or scientist.
