Unfortunately the simple reality is we all have to do something to survive. Whether that's being a hunter gatherer totally removed from modern society, or working 18hrs a day to buy flash cars and keep up with the joneses on Facebook, or something in between like most of us do; the sad reality is that we all (other than maybe a very tiny % like Dave) have to do something other than have fun on the ocean. So while it's a cool vid and all, it's a bit naive and simplistic to suggest we're all blindly wasting our prime years if we're not all having fun on the ocean all day, every day like Dave is. We can't all be "professional watermen".
It's all about balancing ideals with reality. Hating on ourselves for not having fun all day every day seems a bit pointless to me.
But I still wish I was Dave.
