Happiness is not a simple goal. Being happy often means continually finding satisfaction, contentment, a feeling of joy, and a sense that your life is meaningful. So, how to be happy ?
A person can live happily if he is honest with himself and with others and if he chooses everything in his life, if he looks at others with love and tries to help them whenever they need help.
Do things for others without expectation. Follow your values and dreams. Live a well-rounded life. Do things that give you a sense of accomplishment. Take care of yourself.
