Be a reflection of what you'd like to receive. If you want love, give love. If you want the truth, be truthful. If you want respect, give respect. What you give out will return to you. Meaning. It would be best to treat others the way you would like to be treated.
What you give out to people will return to you irrespective of what that thing is. All actions have reactions, either good or bad. So, if you are not respectful, truthful, kind, forgiving, and loving to people, they won't do the same for you. But if you treat people with love, kindness, respect, and forgiveness, they will also treat you the same way.
If you give out something bad, you will receive worse. So be kind, truthful, respectful, forgiving, and loving. If you want to change your life, change your thoughts, and do to others what you would love to be done to you. To have better reactions to your actions, give what you know you would be happy to receive back from people.
