Rubbish. I used to compete in Laser, Flying D and Finn regattas, it was hard work with long days on the water, and very much worthwhile - now, I'm more than happy kicking back in pretty much anything and enjoying the calm serenity of it all - we had a J20 for a while which was minimally challenging, but also very much worthwhile. On the rare ocassion I get to ride these days, I'm not going to telemark my old **** somewhere insane or waste my days on double blacks, I'm going to glide around effortlessly in knee deep powder off-piste - no challenge, but so unbeatably worthwhile. I also very much enjoy sitting on the beach enjoying the sites and sounds around me - a very worthwhile experience imo. So, please do carry on thinking that every recreational moment must be filled with challenge to be 'worthwhile', but you're wrong.
