Smiles are contagious. Test it for yourself. Smile at people and note their reaction. Most people will smile back at you, even if they don't know you! A smile is a universal signal for warmth, friendliness, and bonding. So, go ahead and smile at others. It will make the world a friendlier and more peaceful place.

Remember that your colleagues and team members constantly observe you and your behavior. As a leader, your behavior sets the norm and standard for the organization. Therefore, model the behavior you wish others to adopt.
