Worries.

I know it's unhealthy to worry or rather, silly. For it says, "Do not worry about tomorrow for tomorrow will worry about itself." Well, that's true. But I guess it's only human to worry. At this very moment, you are probably already worrying about something. Don't get me wrong, I just feel that I can also be happy whether or not I am worrying. Therefore, "Don't worry, be happy" cease to be relevant.
