I’ll miss Steve Jobs. I won’t talk about that here because there’s little left to be said and others have said it better than I ever could. He was really something special.

His passing got me thinking about the temporary nature of our existence.

As I write this, 24 hours after we were told of his death, the headlines, the blogs, and the discussions are already moving on. They’re already finding new things to talk about. Life goes on, fast.

Steve’s going to be tough to replace, and he will be sorely missed, but his chair is already being filled.

There’s a lesson in that.

Sometimes I feel paralyzed—held hostage—by my fear of losing someone important to our firm.

What will we do without that person? How will we survive? Who will do the work? These are the questions I ask myself.

Why do I still worry about this stuff?

I’ve been doing this for a long time. I’ve lost good people, and we’ve survived. Yet, I still worry.

I really don’t need to worry like I do—it’s pointless. We’re all replaceable. It’s inevitable.
