Be Humorous and Fun
Everyone wants to be near a person which makes them laugh. Nothing can replace a good laughter! Laughing is a healing process, and it is such a positive emotion.
It brings you joy and happiness, and it connects you with others on a deeper level, so practice this skill.
Try to notice only good things in others and approach life from a more optimistic point! Do not judge and criticize, do not always look into stuff in a serious way, instead, try to smile as as you can.
