Yes, yes and yes
We could easily x3-4 our income if i allowed my huby to turn his hobby into 'work' and I got a part time job.
He works as a postman, he has a degree and could earn more but as a postman he is back before lunch, he helps around the house and is there for me and the kids when they come home.
He's hobby/likes is buying and selling cars, he is very good and can earn £800 extra a week if not more (it would take a lot of time and could cause some stress, if a car was faulty money would be lost).
I'm a student, I only go to college 3 days a week. I could work part time but it would be too much as my health is not great.
As you can see, we can earn a lot more but in doing so we will not have such an excellent family life. I know my kids and huby like the back of my hand. We holiday in the uk or Europe every few months. A good family and family life is better then been dressed up in diamonds but alone.
Once my home salon is ready, I'll be working around my family.
