The core essence of all our goals is simply this:
To be happy.
Luckily, this is an easy goal to attain, because at it's essence, happiness is more of a decision than anything else.
Take a moment now and remember a time when you were happy.
Relive the experience in your mind. Pretend it's happening now, and notice how you feel.
You feel happy, right?
Maybe not ecstatically "out of your mind" happy, but happier than you were just a moment ago.
Sometimes we need to ignore what's going on in the world around us and experience our own happiness.
When we do, we can often bring this happiness into the experiences we share with others, help them be a little happier, and brighten the world one smile at a time.
