So add one more skill to our career advice for young people: be willing to take risks! Perhaps more importantly, be willing to tolerate (and perhaps even encourage) risk-taking in those who are managed by you. Of course I realize that this is much easier said than done. I was a "leaf node" at Sun, and a zillion other places before that. I've even done a little time as a "branch" (and I sucked at it).
But can anything be done about all the spirit-squashing risk-aversion? Recognition is the first step. Unfortunately, those who recognize it tend to be the leaf nodes--the ones with the power to create and implement the ideas, but very little power to authorize them. Those with the most potential to create change are the branches. The Managers With a Clue.
