Various scientific studies have found people who smile often look more confident. This also leads to success in job performance.
Therefore, try to always smile in front of colleagues, customers, clients, to superiors, who may give a positive response from them to you.
In addition to the release of the neurotransmitters dopamine and serotonin, smiling also helps release natural pain relievers in the body, namely endorphins.
The title is so confusing.
