Women please read and comment

I need advice. I love being a stay at home mom. I just feel like I need to be doing more with my life to provide for my kids. (Please don't take offence this is a personal feeling for myself if I could afford to stay a sahm I would)

I don't have a career to fall back on as I have only worked in retail and would love a passion to have as a career. But the problem is I can't figure out how to do that. I would love to have my own business one day and be an entrepreneur. But how do I take the steps to make it happen? Please comment!!
