Intelligence excusitis, or “I lack brains,” is common. In fact, it’s so common that perhaps as many as 95 percent of the people around us have it in varying degrees. Unlike most other types of excusitis, people suffering from this particular type of the malady suffer in silence. Not many people will admit openly that they think they lack adequate intelligence. Rather, they feel it deep down inside.
Most of us make two basic errors with respect to intelligence:
- We underestimate our own brainpower.
- We overestimate the other fellow’s brainpower.
Because of these errors many people sell themselves short. They fail to tackle challenging situations because it “takes a brain.” But along comes the fellow who isn’t concerned about intelligence, and he gets the job.
The thinking that guides your intelligence is much more important than the quantity of your brainpower. Let me repeat, for this is vitally important: the thinking that guides your intelligence is much more important than how much intelligence you may have.
