I agree, the potential is enormous!
Most of the people don't like the 9-5 job.It is a dream to everyone, to be free and do passionate work. But most of us belong to the middle-class family, so it becomes our priority to earn money after completing graduation/masters.
But if someone really wants to work independently, they can start when they feel confident to work alone independently and become successful.
Wish good luck to all who want to work indepent.
