You are not an expert in every subject. Of course I suspect we all know someone who thinks just the opposite. And they are so much fun to be around. In Texas we called people like that graduates of Rice University – a two minute expert. For my friends that graduated from Rice, this is not a cut at Rice or the quality of the education. But rather a play on the university’s unique name.
I ran across this article last week and really enjoyed it. It is from the Harvard Business Review blog. The author thinks sometimes people stretch too much. They accept jobs they may not enjoy or not succeed at.
