What is your reason for getting a license? Getting a license is ridiculously easy, so there are a lot of agents floating around who shouldn't be representing other people. It's OK if you want to represent yourself, but realize the business looks easy from the inside, but it is not, especially if you hope to be good at it. It requires knowledge, time, patience, money, business planning, emotional and financial stability. Yes, getting a license is the first step, but where do you go from there and what are your expectations?
I think having part time agents is also a disserve to the industry. Would you want a part time doctor, lawyer, or dentist to take care of you?
