Happiness is often easy to depict in books but is often the hardest for anyone to feel in reality. This is because life is nothing like a story, but that doesn't mean that happiness is unachievable. The feeling of happiness varies among people and there are many different reasons as to why one would be happy.
In the end, it's how long that happiness is able to last that matters the most. Of course you would want your happiness to last for as long as you live, but the fact that you want to read this book means that you probably don't know what happiness is or how to obtain it.
The truth is that happiness is not as difficult to achieve as you think it would be and this book would explain why.
