Well then we have different views on what a meaningful activity is for us. I don't have an exact definition per se, but it would go along: changing the world for the better, if only by slightest amount. Helping others. Improve myself (debatable since its usually a tough workout and exposing oneself to dangers changes personality a bit for the better).

Maybe its about about direction - inwards vs outwards. Dunno. But climbing some big rock, risking my life definitely doesn't feel like it has big meaning to me. I am not saving anybody hanging there. But it makes me happy. Working for some NGO, being a doctor or improving peoples lives would definitely be in the category of work with purpose/meaning.
