Can Children 12-14 Be Real Estate Agents?

I believe the age from 12-14 is a very naive age and at this tender age children should focus on something else. A real estate agent has a very tough job. He has to meet a lot of people and has to persuade and engage people on different prospects, this is both time consuming and tiring. Children of this age, if they want to get a job, have numerous other options like working at the local store etc, where they can fulfill their limited monetary needs. I believe children of this age need to focus on their education for their better future and being in this profession is a full time job, so they will have to forsake their studies.
