Happiness is something you choose. If you truly want to be happy, you have to choose it. It's a decision within yourself & something no one can decide for you. It's the choice to walk around with a smile on your face or to walk around frowning. It's so much easier to walk around with a smile. The world will look so much different to a happy person than to a miserable person. The easier you make your life, the happier you will be. Don't over think situations, and don't be obsessive.
It's a part of you that decides it's tired of crying & being miserable. To take the next step, smile, and be happy with yourself. Accepting yourself is the first & biggest step there is to take. Once you take it, everything is lifted off your shoulders & you feel as if you're a new person.
Be happy. Life is too short to walk around being miserable. Choose to be new. Choose to smile. Choose to be the person everyone loves to be around! Happiness, it's a new thing to wear. :)
