How to be a good human being?
Always be thoughtful of others. Put yourselves in the other persons shoes. Do not judge anyone based on their color, appearance, ethnicity, education, job etc. Their actions may not look appropriate , but a lot of times it is because they do not know and they are still learning. Be kind and help such folks. If everyone starts doing this , the world would be a much happier place. The happiest places in the world are not with the best weather and infrastructure, it is the happiness of the people living there.
