What Business To Do?

I already planning to resign soon or after my children start to study in primary school. I know I will need more time to fetch them go and back from school also I need time to guide their homework. I did consider to be an online wholesaler that could manage my business at home. My only problem is I have no idea what kind of business to do now! Well, maybe I am not the only one have this problem. My friend just told me the same; she wants to be a home business woman but has no idea what business to do too.
