Has anyone started their own business?

Help! I'm looking for inspiration and some role models, can anyone help? Have you successfully set up a small business in recent years? Are you in your fifties or older? I hope so because there must be lots of other grans and grandpas who don't have jobs (either by choice or circumstance) but aren't ready to accept retirement. There are lots of stories in the media, blogs etc about young mums setting up kitchen table businesses making cupcakes or sewing bags or whatever but where are the older generation? Or maybe the over fifties just consider themselves too old?
