Smile can be very contagious, sometimes you can’t resist giving it back. You will brighten the days of people around. You can calm your own fears and anxiety and be more productive in all areas of your life. You don’t necessarily need a good reason for smile; maybe a woman on the painting doesn’t have it, but she still chose to have this positive moment. Even when it means to go against your own subconscious thoughts, you need to shift a mood and remember that we all need that smile more often than we used to think.
