Write because you love to write not because you want to be famous or wealthy or for any other reason other than you can't help yourself. Keep at it and hopefully someone will pay you something someday!
Or your 10-year-old daughter will wander into your bedroom one morning and say: "Momma can I read you the book I wrote? And will you help me get it published?"
That is a special kind of famous, a different kind of wealth.
