Create Anyway - The Joy of...

Ashlee Gadd

Motherhood and creativity can coexist. 
 
  
 
You have creative dreams swirling in your heart, but pursuing them while changing diapers and managing the carpool schedule feels impossible. You have no time. No space. You can mother, or you can create. You certainly can't do both (right?!).

This book is a much-needed permission slip to do just that—through the pictures you take, the stories you write, the meals you make, the music you play, the gardens you grow. 
 
  
 
In this unforgettable book, writer and mother Ashlee Gadd helps you set aside the guilt and discover the sacred connection between creating and mothering. One-part commissioning, one-part pep talk, Create Anyway will propel you forward with a renewed sense of energy, purpose, and enthusiasm for stewarding the creative dreams God has planted in your heart—right alongside the diapers and carpool.
