A confident smile is a happy smile. Have you ever had a stranger smile at you while you were in public? Maybe you were feeling down, but their genuine, friendly smile literally turned your frown upside down. All thanks to that random smiling person, your negative attitude suddenly subsided.

Well, when you smile at someone, you may feel like you are experiencing momentary happiness. This is because endorphins are released in your brain when you smile. Endorphins can be described as natural painkillers for the body, which also increase our self-esteem. Smiling really is a simple act of kindness, which can also make you feel better about yourself. At the same time, freely showing off your pearly whites is something that many people are insecure about doing. After all, your teeth are one of the first attributes people notice about you. When you're out to lunch with a friend, it's no fun having to worry about how your teeth look when you laugh. Obsessing over other people's smiles because you're unhappy with your own isn't worth doubting yourself. So smile and bear it, because you're adorable when you're happy. For example, someone who shows up to a job interview with their head held high and a smile on their face will have a better chance of getting the job. Employers point out that a person who lowers his gaze when speaking to avoid showing a smile during an interview will most likely not be hired, because it seems like he is hiding something. Instead, that person with an inviting smile exudes a confident demeanor. It doesn't matter what you look like, a smile is worth a thousand words and people recognize it.

I truly believe that a bright-eyed smile has the ability to allow you to connect with others, without making a sound.
