Undemanding and Typical Life

I don't desire my children to be as gifted as Albert Einstein.

Yes, this is true and I have a valid reason why I don't desire my children to be as gifted or great as German physicist Albert Einstein. Call me a freak, but I would desire my future sons and daughters to live a typical and happy life. I desire them to enjoy and appreciate every moment of their youth so that when they become adults, they can share their experiences with their children. I also desire to see them playing with other kids instead of locking themselves up in their rooms and memorizing the elements of the periodic table and the various chemical reactions. I don't desire them to be extra gifted like Einstein because they might not be able to handle fame and greatness well.

As a parent, I just desire my children to lead a normal and undemanding life. Of course, I desire them to be intelligent and dynamic someday but in minimum level. I don't desire them to be a genius and master of everything because I desire them to enjoy childhood. Is that too much to wish by a parent like me who just desires the best for his children?
