Do kids naturally hold the keys to a good life?

My kids are still young, respectively 4 and 2 years-old. The more I observe them, the more I tend to think they already hold all the right keys to live a good life. A few things here: it's not about 'my' kids, but kids in general. Since mine are the ones I observe the most, on a daily basis, of course they're the ones I might refer to the most. Then, when I say 'holding the keys to a good life' I mean: they already possess, play and use all the right ingredients to live life at its fullest but of course, everything is still raw. Hence childhood by the way, as a time to mature, learn, develop and we - adults - have such an important role to play here.
