What does Happiness means?

Dear sisters, i m currently reading this self reflective book which i think is quite good. So, i m gonna share some of the stories with you girls.

In the book, the author asked some students why they worked so hard. And, unanimously, they replied that their hard work will help them get into the best possilbe colleages. And when the author asked why, they replied "so we can be happy". This is what he wrote...

What are we really hungry for? Security and happiness, yes. But the kind of securtiy we yearn for is a feeling of security that cannot be attained by acquisition. If we can buy big houses and powerful cars, we may be able to achieve the illusion of security, but it is still just an illusion. If we can do well at school or work, we may get a sense of accomplishment, but there will always be something more to accomplish - happiness will always be around the next corner.
Real security only comes when we are comfortable with who we are (and the feeling is enhanced when we are in a relationship where there is mutual love and understanding). Real happiness is a byproduct of a life well lived.
Remember what your soul needs. Not wealth, prestige, and possessions, but the adult responsibility to love someone everyday a little more than you did the day before.
-Letters to Sam

So sisters, it's you girls who made me feel comfortable. And you girls who gave me happiness.
I Love You!
