I remember having a conversation with an older wise lady when I thought about returning to work outside my home.Saying to her that I wanted to be at home for my school age children coming home .She told me that it is the quality of parenting and not always being there as long as they were cared for by a responsible adult..
That was sound advice
Need you run a business ? could you work for another person without the whole responsibity for a business.The experience you gained from setting up your venture wont be lost..
