Everybody wants to be happy, but what is happiness? One of the most widely recognised theories of happiness, is Martin Seligman’s PERMA-model, which posits five elements of psychological well-being:

  • Positive emotions (feeling good)
  • Engagement (experiencing flow, using your strengths)
  • Relationships (connecting with other people)
  • Meaning (making a difference)
  • Achievement (accomplishing something worthwhile)
