A speaker or writer uses myself to refer to himself or herself. Myself is used as the object of a verb or preposition when the subject refers to the same person. I asked myself what I would have done in such a situation I looked at myself in the mirror
emphasis You use myself to emphasize a first person singular subject. In more formal English, myself is sometimes used instead of `me' as the object of a verb or preposition, for emphasis. I myself enjoy cinema, poetry, eating out and long walks I'm fond of cake myself
emphasis If you say something such as `I did it myself', you are emphasizing that you did it, rather than anyone else. `Where did you get that embroidery?' --- `I made it myself.'
