I know that "myself" is a reflexive pronoun and can also be used for emphasis. When writing something to the tune of "I myself would love to go hiking." Wouldn't it be proper to use it as an interjection "I, myself, would like to go hiking." An interjection of this sort would typically clarify to whom the pronoun is referring, however "I" is already a clear indicator of who I am, without the "myself" attached.
TL;DR: Shouldn't I be using interjection commas for the phrase "I, myself, ..."?
