Today in class we talked a little bit about the pursuit of happiness not being merely a right but also a responsibility. Unhappy people tend to trigger unhappiness in others. Happy people are a delight to be around. So striving to be happy is not a selfish undertaking at all.
Happiness cannot be traveled to, owned, earned, worn or consumed. Happiness is the spiritual experience of living every minute with love, grace, and gratitude.
Of course, it must be remembered that we are talking about real happiness here - not mere gratification. And a lot of people confuse the two.
