Martin Seligman’s view that authentic happiness comes from using your character strengths makes sense to me. For example, it seems reasonable to expect that activities that would bring lasting happiness to a person whose strengths are curiosity, love of learning and zest would differ from those that would bring lasting happiness to one whose strengths are kindness, fairness and a forgiving nature, or to one whose strengths are judgement, perseverance and leadership. (In his book ‘Authentic Happiness’, Seligman identifies 24 strengths under the general headings: wisdom and knowledge, courage, humanity and love, justice, temperance and transcendence.)
