Doing acts of service, like charity work, can lead to a serotonin rush and happiness. Success does not always lead to happiness, but happiness can lead to success, especially in relationships and love. Happy people are more likely to give and donate to social causes and individuals in need without expecting anything in return. By being more loving and giving, the happier you become, creating a virtuous cycle of happiness.
