Happiness is a choice. You yourself can CHOOSE to be ecstatic or you can choose to be depressed. It's up to YOU. I know that's easier said than done... but there is an easy little trick to help you out.
Just SMILE. A smile can BRIGHTEN your day and it can do the same for someone else. The second you smile, you exude a certain BEAUTY, a LIGHT.
Think POSITIVELY and everyone will be able to tell! Seriously. If you are happy, truly happy, you can help someone else become happy. Happiness is CONTAGIOUS!
Being happy and KIND may seem like no big deal... but to others, your attitude will effect them! If you are nice to someone, even in the most minuscule way--holding the door, smiling at someone, talking to them when they seem lost-- it could really impact how they are feeling!
I'm sure you had someone do something tiny that just made your day! Maybe a stranger commented on your new jeans that you love. ANYTHING at all can add some LIGHT to someones darkness. One thing that's sure to put some light in someones day is CHRIST.
Go into the world and SHINE YOUR LIGHT, the light that God has given you-- I think you'll be surprised by the results.
