There is nothing wrong with teaching, providing your
students are all aged 18 + years; better still 25+. Such
students are volunteers and (usually) wish to learn,
unlike schoolchildren who are under duress, and whose
parents have no interest in education, unless they are paying for it directly.
Adult education is very rewarding, esp. In Higher Educ-
ation. I wouldn't have changed it for any other job, but
my initial experience in child education was a trial and
torment, but......if you are a masochist it might just
suit you.
