Whining, complaining, venting, frustration, anger, jealousy, and bitterness are the antithesis of happiness. These never produce joy, even in the slightest.

Yet, when other people succeed, it is natural to feel these emotions, especially if it is someone we do not particularly care for. 

Being happy for others increases your happiness. 

Finding joy in other people’s accomplishments and successes, even if they are not friends, still increases your happiness.

You cannot fill your soul with negative attitudes and expect it to overflow with positive emotions. Only by genuinely being joyful for others will you experience the happiness you long for.
