It is not bad to be selfish as your first responsibility is to take care of yourself. Only when you are satisfied and happy, you can make others happy and become selfless.

Happy people never compare themselves with others as they are satisfied with what they have and what they are. They have a feeling of completeness as a human being. Once you are complete, you are peaceful and happy.

The most gratifying relationship is often found between a husband and a wife. They can be a lover and a friend to each other. Often wives care for their husbands like a mother and husbands protect their wives like a father would. It is for this reason that when people fall in love, they feel elated and satisfied as they find almost all kinds of emotions present in their relationship with their beloved.

Every person who is satisfied, content and happy thinks his understanding of happiness is truest because that is what he is experiencing. So, a virtuous person would subscribe his happiness to his virtuous deeds while an evil person would subscribe his happiness to his vices. Since a corrupt person has never lived a virtuous life, he will possibly never know the euphoria one derives from doing good deeds.
