A smile can go a long way to boost your confidence, and it's also a great way to express the acceptance of others. According to a
study, it takes 113 muscles to frown and just 12 muscles to smile. Make it easy on yourself, and smile.
When you smile at someone, you send a signal of openness and friendliness, which in turn may translate into a meaningful conversation, friendship, or business relationship.
If you are a shy person, it can be daunting to increase your confidence level, especially in front of others. Practicing maintaining eye contact can go a long way and help boost your other confidence skills.
