Identify what it is that being a good person means to you personally. Some people think that being a good person is as simple as not doing harm to another, but it is not always about what you don't do, but what you do for others. You might not be a bad person, but are you a good person?
Who do you look up to and why? How are they making the world a better place to live in, and how can you do the same?
What qualities do you admire in them, and how can you develop the same ones?
Keep your role model close to you, like a friendly spirit that is always at your side. Think how they would respond to a question or circumstance, and how they would respond in the same manner.
Think of ways that you can better embody these qualities you admire. Think of how to apply those qualities in your work, creative pursuits, personal relationships, diet and lifestyle.
