Happiness is a cause...

Happiness is a cause, not a result.  Which explains why there are plenty of people who appear to have every reason for happiness, but are in fact miserable. And there are others who seem to have no reason to be happy, yet they are as happy as can be.
There are many people that find themselves waiting for a reason before allowing themselves to be happy.  The problem is that reason will likely never come. But when you find yourself able to be happy even though there’s no reason for it, pretty soon an abundance of reasons will start to appear.
When you choose to smile, there will be much to smile about. When you choose to be thankful, there will be plenty of reasons for being thankful.  Remember that happiness is a cause, not a result.  Don't make your happiness conditional.  When you do, you’ll limit it and drive it away. 
So instead of waiting for happiness to flow toward you, let it flow from you. Such happiness will never fail to find its own very good reasons. After all, happiness is not a result....it is a cause.
