When you're having a rough day, it's easy to forget just how awesome you are -- but luckily, a mysterious Los Angeles street artist is on a mission to remind you.
"I was pleasantly surprised to find the first one and as I kept walking I realized there were more," Blazenhoff told HuffPost. "It was lots of fun to follow the trail of good wishes and photograph them all!"
We're not sure who did this and why, but we really appreciate the effort. Sometimes, a little encouragement from a stranger is enough to put you back on top of the world.
We're already smiling. Are you?
Now, go get 'em, tiger!
