Myself - used for emphasis, my own self or person; as I myself will do it; I have done it myself; -- used also instead of me, as the object of the first person of a reflexive verb, without emphasis; as, I will defend myself.
It is perfectly ok as long as it refer to subject of the sentence. When it does not refer to the subject of the sentence as: He was an enthusiastic fisherman like myself. such usage is not appropriate though some people like to contruct sentences this way.
