Saying hello to someone, even if you don't know them, is a common courtesy. It means you are acknowledging their presence; you are saying that they are a person, too, and that they are important enough for you to say hello to.
Often we are tempted to keep our heads down and focus on our phones, blackberries, or i-pods. We would rather talk to people we know, miles away, than say hello to the person who is physically present with us. It is time to change that. Say hello to the person next to you in the elevator, or on the train or bus. Say good morning to people as you walk by their offices on your way to work, even if they aren't your favorite co-workers.
By saying hello, you are letting that person know that you noticed them, and that they matter. What a compliment!
Don't stop at "Good Morning." Start a conversation with the other person, ask them how their day is going, or what their weekend plans are. Who knows, this person might just become someone special in your life, all because you took it upon yourself to say hello one morning.
If you are shy by nature, you can simply say hello to the people you pass walking on the street. Just make eye contact and smile or nod. That is enough to make someone's day!
