- First, a sharp mind begins with preparation. Rehearse. Do a mental run through. If you avoid thinking about a situation that makes you nervous, all you're doing is rehearsing being anxious.
- Next, if you make a mistake, don't think, "I look stupid." Instead, do something constructive immediately. For example, if you're speaking to a group, stop and look at your notes. And don't forget to breathe deeply. Tension makes our breathing shallow and irregular.
The same is true for exercise. Instead, stick to your routine and make these changes right after the speech, exam, or interview is over.
