"Keep your face always toward the sunshine and the shadows will fall behind you."
It's hard to be optimistic sometimes, really hard, but I would rather strive to live my life as happy as possible than be miserable. Sure, some days I just want to sit in my bed and wallow, but usually I have too much to do and am unable to do that. So instead, I take a little bit of advice from Walt Whitman and find the sunshine in my day. I keep this quote in mind often and it usually reminds me to think positively and live my life to the fullest.
