you know, some of us DO hangout around lake geneva (or any other pretty place), have most of weekends done like there's no tomorrow (mountains, adventures, traveling etc. practically every weekend) and still manage to invest into whatever they prefer (right now selling flat in Prague, and considering one in Chamonix). That's my sweet spot in life right now. We'll see how long life will keep me in it, before throwing into something wild, as usual :)
It's not irresponsible to spend money on traveling and adventures. You get back much more than nice time there and couple of photos and souvenirs - you are exposed to new environment, people, culture etc. and you'll grow inside in a subtle, yet steady way. On the other hand, usual "buying stuff you don't need to impress people you don't care about" is useless, and won't even bring any long term happiness.
