In life, my lips never know my problem they just always smile. Because, life is a tragedy when seen in close-up, but a comedy in long-shot.
Life is a play that does not allow testing. So, sing, cry, dance, laugh and live intensely, before the curtain closes and the piece ends with no applause.
Finally, a day without laughing is a day wasted, and you'll find that life is still worthwhile if you just smile.
