3 happiness paths.

Are you doing any or all of these?

• Feeling good. Seeking pleasurable emotions and sensations, from the hedonistic model of happiness put forth by Epicurus, which focused on reaching happiness by maximizing pleasure and minimizing pain.

• Engaging fully. Pursuing activities that engage you fully, from the influential research by Mihaly Csikszentmihalyi. For decades, Csikszentmihalyi explored people's satisfaction in their everyday activities, finding people report the greatest satisfaction when they are totally immersed in and concentrating on what they are doing — he dubbed this state of absorption "flow."

• Doing good. Searching for meaning outside yourself, tracing back to Aristotle's notion of eudaemonia, which emphasized knowing your true self and acting in accordance with your virtues.
