Jack Dorsey tweeted,

We welcome risk when we're young, we avoid risk when we're older. People, companies, governments: only a determined few break this pattern.

Jack's heart is clearly with the risk takers. But I think there's a more measured way to read this tweet.

Perhaps with age comes the wisdom to be more careful about which risks are worth taking.

I believe it's not avoiding risks that we favor as we age; it's managing risks.

@ifindkarma That's because as we get older we turn into Squares.

Therein lies the rub, though, doesn't it? It's awfully hard to know which risks are worth taking with any certainty. If we knew, they wouldn't be risks.
