Accepting others in your life means really respecting their ideas when you do not agree with them. When a person put rules and expectations from others, he is really making it hard for himself to have friends and he is limiting himself from exploring new ideas in life just because he had put a label on others according to his brief information of them. I think this way will limit his experience in life.
A person should accept other people’s opinion when they do not have the same opinion as him. Accepting others in a person’s life means accepting the fact, they have the right to show their opinions, ideas and beliefs in front of you even if they are not agreeing with you they should not feel threatened.
Usually, when a person accepts a certain person in his life, such as a friend it should mean he accept his flaws too, even though that does not mean a person does not try to improve himself but I mean he should not always point out his friend’s flaws all of the time. Ironically once a person admits his flaws to himself, he usually tries to improve them.
