Mrs. McMoanypants

So here’s the thing: I work full time, which means that I’m out of the house for at least ten hours a day.  I dislike my job intensely.  I would rather be at home making “stuff”.  I’m convinced that I can make a living out of this. But I have to make a start somewhere.
I just don’t know how to work a full day, cook dinner, spend time with the girls and my husband and still “start somewhere”.  I do make some stuff over the weekends, but there’s always other things to do: school sports days, someone’s birthday, shopping to do….
I just don’t know how.
Please help?
