Learning to swim starts early for most
Agree that it's a huge problem, but super majority either have it or they don't, so a bit of advice is like a bothersome mosquito--this lesson starts early. Others do (have it) but are in an enterprise culture that doesn't encourage or incentivize any risk or initiative. As is often the case, what majority perceive as low risk usually isn't--for their own careers and organizations. Risk averse cultures quite literally can't provide value--often translates to a negative value in IT, and so many have become more of a liability than an asset. This includes some CIOs in the largest organizations--including IT giants, who admit publicly to not even taking risk their CEO is requesting!
