A kindness, any little thing that helps others, such as giving up your seat on the subway, helping the elderly cross the street, helping the mother cook, smiling at strange children and not spitting, can be regarded as a kindness. Everyone can write down the good things you have done for others. Don't always help silently, share together and praise yourself often! You can also write down stories that you see others helping others. Maybe you don't have time or ability to help, but all your friends have done it. You might as well help them publicize it and praise it! (all)
