Honest, you shouldn't be worrying about this.. your ten. BUT here is some advice;

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 ?
Every day, try to do an act of charity for some one else, even if it's something small. Even reach out to people who have been cold or indifferent to you. An act of kindness and generosity can go a long way. 

Be respectful of elderly people. Realize that you will be old some day and may need a helping hand. Next time you go to a mall, parking lot or any where, focus your vision all around, look for an old person struggling with something: like carrying bags or loading groceries into their car, and say " May I help you with that Sir or Mam, and you will be doing a great service for Seniors. Sometimes you may get one that is crabby or doesn't trust another, and will refuse your offer, then simply say " I understand Sir or Mam, and I wish you a good day " Don't give up at this point, and keep up looking for one that will accept your offer. Realize that the elderly can have vision, hearing, or even dementia problems, so you may need to gesture with your hands as in carrying or loading. Go to a park and take a brisk walk, and if you see an old person all alone, say hello with a gentle smile, and ask how they are doing, just acknowledging someone is only proper, and can really make their day. 

Try to imagine loosing your spouse that you enjoyed and loved for many years, only to be left alone in the big world all by yourself. By developing this type of attitude of love and understanding for the gentle things of life, like the elderly, you be on your way to the true meaning of life and sharing, and you will become a better person. 

Be compassionate towards mentally challenged people for they are people with feelings to, and they are brothers and sisters as well. Act as if life is just a chance, and you could of been born the same way, and if you were, how you would want to be treated. They too have a sense of feeling, so give them a big smile, and show loving compassion with your eyes. Be careful not to touch them though, cause sometimes this can scare them. If other people are around that are smiling or laughing with your interaction with them, ignore them and keep your attention on your brother or sister that is your true friend. 

Love yourself. Practice unconditional self-acceptance. It is a lot easier to love others, but first you have to have confidence and love yourself. You can do this by going out in the community and offering small acts of charity, then gradually increasing them a little at a time. Do not try to do too much at once, but take it in baby steps. You will start to be a better person when you can put a smile on someone's face and make their day, and it will make yours as well. It has been said that it's in giving that we receive.
