Teaching is one of the traditional careers persued by those who may not have adequate info about other avenues of life,and those with the fear of the unknown about professional life.
Teaching is a noble profession and has to do with assisting,not serious business.
It is not a lucrative career,and unless a teacher starves himself,he may never find cash to invest.
Many teachers are not wise investors,and will most probably fail in their investment endeavours.
Teaching does not carry with it the prestige endowed in other careers.
Teachers are at the disposal of every Tom,Dick and Harry,and often rub shoulders with them,perhaps this is the reason why little respect is accorded them. Some say it is one of the professions associated with Jesus. Others being carpentry and forces. They carry some nobility. I would not advice my kid to persue it.
Teaching however is very fulfilling when you see your products blossoming as much as you may never enjoy the fruits with them.
...the proverbial tortoise and hare...
