Stay calm. Learn to forgive. Think about how others feel. Trust that you are a good person.
Nice guys are not hotheads, so if you have a problem with anger, you need to start working on it. Getting rid of anger will not only help others perceive you as a nice guy, but it will also help you feel much happier. Yoga and meditation can help you calm your mind and release stress, so consider incorporating these into your routine if you need more calmness in your life. In order to feel like a nice guy, it's important that you not hold on to grudges. No matter how badly another person has hurt you, make the decision to forgive instead of seeking vengeance. Forgiving does not necessarily mean that you need to accept the harmful action as acceptable; it simply means that you need to make the decision to not let the action affect you any longer. Forgiving is easier if you can start to think about the person who harmed you as a good person who did a bad thing, instead of villainizing the individual. Nice guys are not self-centered, which means that they are always aware of how their words and actions will affect others. If you want to be nicer, be sure to always take other people's feelings into consideration. The most successful nice guys consider how others think, how they feel, and how they are likely to act. This helps them engage with others in a way that is both kind and effective. When you think about how others feel, being polite and respectful should come naturally. If you think that something you say or do might be offensive to another person, don't do it. No one is perfect all the time, and it can be easy to think that you are a bad person just because you lashed out at someone or did something else that you're not proud of. Unfortunately, thinking that you are a bad person makes you more likely to act like a bad person in the future, so it's extremely important that you don't judge yourself too harshly. The next time you do something that you're ashamed of, remind yourself that you are a good person who did something bad and that you will try not to do that bad thing again. Do not fall into the trap of believing that one bad action is a reflection of who you are as a person. Keep in mind that feeling guilty about doing a bad thing is an indication that you really are a good person. If you were a bad person, you wouldn't feel guilty at all.
