It's often hard to see ourselves objectively. We're always criticizing, we're always caring about every little flaw. It's easy to get caught up in that downward spiral of critique after critique after critique. It's good to sometimes take a step back, chill out a little, and smile, because we're alive in a beautiful world full of opportunities and potential. And we are full of potential.
Elianna has a book about a girl who is obsessed with the fact that she does not have dimples. She is tormented by this terrible flaw in herself and goes to great lengths to try and fix it. I don't remember quite how the book ends, but I think the point is - you can have a beautiful smile, even if you don't have dimples. It's good not to get caught up in those little "imperfections" most people don't even notice or care about. We're all unique people and what makes one person great is not necessarily what is going to make you great. It's good to focus on what makes you great, not on acquiring something that works for someone else.
Whether you have dimples or not, never forget to let yourself smile. :)
(This car, clearly, has dimples.)
