Self doubt

I am going through a small phase of self doubt. Am I doing the right thing? Have I taken on too much? Am I being a good Mum?

This isn't easy but it is fun. I wouldn't change anything for the world.

I read an interesting article however on "Pressures of modern life driving people over the edge"
I am not saying I feel pressurised as such but I do feel there is more to life than working and money. It states " What we are missing in our society isn't the wealth that we typically crave but meaning."This to me is the crucial part, meaning. What is my meaning? What is Isabellas meaning. Even though we are not at school, I still want her to work hard and achieve certain things.....but Why? Why do I work and try to achieve things? What is my meaning?

I do feel a certain amount of pressure, (completely instigated by me) to find this meaning for both me and Isabella.
