Being nice will give you a lot of friends. However, there are other ways of getting friends. Some of these ways include joining a sports teams and social networking. Engaging in a hobby will also get you a lot of friends whom you share common interests.
That isn't all.. You can not be to nice to people because they will just take advantage of you and use you! They will only talk to you at certain times like if they need things they will not be a true person towards you.
