Happiness belongs to those who are sufficient into themselves. For all external sources of happiness and pleasure are, by their very nature, highly uncertain, precarious, ephemeral, and subject to chance.
We are all interdependent; our friendship and interactions are precious and can be sources of great joy. But, we cannot depend so much on others that we need them to make us happy.
The happiest people simmer with gladness regardless of whether they are in happy circumstances. A healthy self-sufficiency is the first step in developing an unshakable sense of joy.
Sometimes I feel happy because of a conversation, event, or enjoyable activity. We don't have to rely only on those sources of happiness, however. we can find happiness within ourselves.
