What are your favorite inspirational quotes?
I like to write quotes on my planner's weekly pages to inspire me, keep me motivated, or just keep my perspective. Also, I've decided to expand the Me section of my Filofax into an entire Me notebook, and I'd like to have my favorite quotes throughout the book.
So let's hear it! What are your favorite quotes from famous, or not so famous people about life, the universe, and everything?
