Happiness is the main thing behind which the whole world is running; however, only a few lucky people succeed in finding it. A majority of people never succeed in finding true happiness and died as sad souls. Do you know the answer that why it is so and Why so many people fail in finding happiness? The answer is very simple that they search for the Happiness at the wrong place. For whole life, they run behind the people, things, and wealth that they get no time to understand that these things are essential but they don't have the power to make us happy.
Happiness is not something which can be bought or someone can gift it to us, however, happiness is an internal business which only depends on us and we can only find it inside us. But, very few understand this simple thing and keep on looking for the happiness in the outer world in the material objects or in the people. Such things may provide temporary happiness but they can't provide us true happiness because they have no power to do so. We all are full of happiness and this happiness doesn't depend on anyone. Only, we need to relate to our inner self (true self) to find this happiness. I have already explained this topics in past at To find Real Joy of Life and Long Term Happiness Vs Short Term Happiness.
The other common reason of unhappiness is people either stuck in the worries of the past or of the future. To enjoy life, it is very important for any person to start living in the present moment because we can't alter our past and future is totally unseen. So, why spoil our present by worrying about the past and future. Moreover, when you waste your present life, then you also ruin your future because our future is the outcome of our efforts done in the present.
"Happiness cannot be traveled to, owned, earned, worn or consumed. Happiness is the spiritual experience of living every minute with love, grace, and gratitude. - Denis Waitely"
It is a difficult thing to keep the focus of our mind on the present moment because it has the habit of running either into the past or in the future. Moreover, when we are sad or worried, then it becomes even more difficult to keep our mind in the present moment. However, those people who succeed in keeping the focus of their mind on the present moment, they open the door of happiness for themselves.

We can't succeed in finding true happiness in life till we keep on searching it at the wrong place. We need to develop clear idea of what makes us happy and what makes us unhappy; otherwise, we will keep on running in the wrong direction and actually going away from the happiness.
