What is your definition of a single mother? Being a single mother is not a setback for success.
Too many women use the phrase "single mother" What is a single mother? Does this set you back from your visions, goals, dreams? Remember in the "old" days? Women would give birth to children and go back out to the field or back to the regular duties of house cleaning, cooking etc. There is single fathers too. Give me your feedback...This could be the final chapter topic in my new book entitled "Tomorrow Starts Today"
Your question appears ambigious. I would say that being a single parent means that the person has a child, but isn't married. Being single isn't a set back because there are blessings that come with each stage of life. When I was single and with no children, I did many things; but now that I'm married, I am still doing many things but its related to building and maintaining a home for my family.
I suppose it depends on the person and how they view life's different stages. I say that no matter what stage one finds themself, we should enjoy and be contented until we go to the next level. I hope this helps.
