Welcome people with an open heart. Don’t be quick to judge,people are different and in most occasions you will be surprised at how much or how often you misjudged people in the past.
An open heart goes a long way than you think. Sometime a small tiny bit of kindness that you did not even know at that particular time can be so much to someone else. Treat others the way you would like to be treated by both people you know and strangers.
