Women who made their mark later in life

Did you know Laura Ingalls Wilder was 65 years old when she published her first "Prairie" book???

It's Women's history month! All week long, I will be telling stories about women who made their mark on the world in their later years. It's never too late to start dreaming. Today, I would like to introduce you to Laura Ingalls Wilder.
When I was in elementary school, Little house on the prairie was a huge part of my childhood. Although the tv series ended in 1983, reruns were aired all the time. Then, in first grade, my teacher read us "Little House in the Big Woods", and I was hooked on the book series.  I still have my little yellow box set of Laura Ingalls books which have been read so often that the bindings are loose and covers are tattered. 
I feel like most people my age know who Laura Ingalls was, but for those that may not, here's a quick summary:
Laura Ingalls Wilder was a pioneer. She and her family traveled west from Wisconsin and settled in the Dakota territories in the mid-late 1800s. 
Laura's daughter, Rose, encouraged her to write about pioneer life. Rose had heard all of Laura's wild tales of life on the prairie and knew that these stories should be published - even though Laura thought them mundane.
Laura was 65 when she found success in publishing. She went on to write and publish 9 books which got her family through the depression and let them retire without financial worry.
So what are you afraid of? What have you always wanted to do?
