Motivation Monday: Happiness

Mondays aren't always the easiest days of the week. Sometimes I feel like I need some serious motivation to get my Mondays going. Do you ever feel that way, too? 
Today, I'm sharing some Motivation Monday thoughts. I stumbled upon this quote somewhere online last week--I think on the cover of a planner I was looking at--and I really liked it. So, I played around in Photoshop and designed a graphic for it. Maybe it will inspire some of y'all too. (And it was a nice opportunity to practice my graphic design skills.)

How do you motivate yourself on tough days? Do you have a favorite inspirational quote?
