Talking To Yourself
If we caught someone talking to themselves, we should not consider them crazy, but they were intelligent. Research showed that speaking to ourselves loudly would enhance self-control. In a study, participants were provided multiple tasks that had instruction. They could try to read what was written loudly or softly. The outcome was the participants who read them out loud had a better effect during the competition.
Alone Is Good
If we were a person who liked to be alone rather than being with people, we might be a bright person. According to psychological research, there was a relation between being alone and intellectual. If we spent the time alone, we could have time to think about an idea and priorities. The research claimed that bright people were not satisfied being around an individual.
