Enjoying being a parent @ 40....

Well middle age has hit me and a career change is on my mind.  I like money as much as the next guy, but the most important things to me these days are my children, my health and living a stress free life.  I have recently started taking a Salsa class with my oldest daughter and a creative movement class with my youngest daughter,  I have entertained the idea of a yoga class as well.  My idea of a stress free job is being the owner of a multi purpose space including yoga classes for young and old, an arts and craft space  for up and coming young people to make, display and sell their crafts, a cafe and book store with  a small flower shop on the side LOL.  Talking to people all day and enjoying the peacefulness of people practcing their yoga poses , smells of coffee brewing and the sight of beautiful  flowers, the sounds of people laughing and conversing would be my idea of a the best job in the world. I am currently a general manager for a major retailer with much day to day stress and pressure.  This is the path I have chosen for myself, but now at 40 ish I am learning who I am and what I enjoy, but the catch is I need to provide for my girls as I am a single mom with no support. 
I am going to keep pondering this idea of a multipurpose space and who knows what may happen....
