Jack of All Trades

“Jack of all trades, master of none…”

How many times have you heard that in your life? In your career as an engineer? I’ve probably heard it hundreds of times, if not thousands, from working on RADAR and various sorts of radio and other electronics in the US Air Force to as recently as last week. There seems to be a feeling that if you can’t know one thing really well unless you somehow give up on knowing a lot of other things — perhaps there is some sort of limiter in our brains that keeps us from learning more than a certain amount of “stuff” in a single lifetime, or some such nonsense. We’ve all seen the Sherlock Holmes moment, for instance, when Sherlock says something about not remembering something because he has so much other stuff to remember.

And we come back to this idea: Jack of all trades, master of none.

Now I’ll readily admit that I only have so much time to read, and therefore to learn new things. I have four or five wish lists on Amazon, each of which has more than 100 books on it. I have a reading list in Logos Bible Software that’s somewhere beyond 100 books. I have a reading list in Safari Books that’s quite long, as well. I subscribe to some 15 or 20 magazines and journals of different sorts, from theology to technology. And I subscribe to a dozen podcasts, and something more than 100 RSS feeds.

And I can read about 60 to 100 books a year. I’m obviously a little backed up on my reading.

But it’s important to be lateral as well as deep. Take a look at the chart below; it might help explain what I’m talking about here.


One thing I can tell you is that as network engineer (or just about anyone living their lives, in fact), it’s important to target the chart on the far right, rather than the one on the left or the one in the middle.

What you want to become is what ol’ Ben Franklin really said:

Jack of all trades, master of one.

    You mean with the right chart , if topics increase overall knowledge will decrease ?. If I understood correct , I don’t agree with that since I am a strong believer of the opposite.

      I mean that given the limited amount of time you have to learn things, you need to learn to balance between between an extreme expert at one thing who knows little about anything else or knowing a little about everything while not having an area of expertise — and you need to keep that focus as you increase your knowledge.

    Very interesting topic. I think you might find this special issue of Scientific American Mind of interest, regarding this topic. Other interesting articles as well in this issue regarding limits etc..

    This article is interesting regarding creativity. In a nutshell, forget what you know.
