How to be nice

These are some ways you can be nice:

Exercise Forgiveness
Forgiving others and letting go of old grudges can help you move forward with a more positive attitude. It's easier to be nice when you like yourself. Forgiving yourself is also essential, so work on letting go of negative experiences from the past that are preventing you from cultivating a more positive mindset.

Be courteous
Politeness is only one aspect of being nice, but it is an important way to start conversations off on the right foot. Remember that the actions of others do not have to detract from your own.
If others are being abrupt or rude, responding politely can help to change the course of the interaction. Simple words like "please" and "thank you" can go a long way in showing someone you appreciate them in everyday conversations.

Practice Gratitude
Spend a few minutes each day reflecting on something you are grateful for. Keeping a gratitude journal may be beneficial to you. According to research, gratitude can have a variety of health benefits, including stress reduction and increased happiness.
Focusing on positive thoughts can help you develop a more positive attitude and make coping with life's daily hassles and difficulties easier.

Take Care of Yourself
The way we treat ourselves, including our self-talk, has a significant impact on how we treat others. After all, how can we be nice to others if we aren't nice to ourselves? Take note of how you speak to yourself and how you react when things go wrong—do you blame or punish yourself? Do you criticize yourself? We make it easier to be nice to others by practicing patience and kindness toward ourselves.
