I think that would depend on a few things:
1) The personality of the person.
Does this person have the drive to start their own business. It's not easy.
2) Their family's needs and desires.
I think it is important to make sure the entire family is on board, because there will be times where it will not be easy.
3) Their financial situation.
Is there extra money to start the business or will it take money away from the regular household budget.
Just my two cents,
R.
