How many types of lying?

To fulfill a lie: The statement must be untrue. There must be an intention to deceive. An effort must be made to deceive. The other person understands the meaning. One person says something he didn't intend to do. Realizing what he said was not truly right, he did what he said in order to fulfill what he has said. An example, someone was given a pamphlet and says "will check it later", do not want to be a liar, he check it later although he doesn't want to check it in order to fulfill what he already said. If he just said without doing it, that is a lie. But what if do it later, will the lie cancelled?
