Differentiating between "me" and myself" often gets people into a grammatical pickle, whereas most people have the usage of "I" down pat.
"I" is only ever used as a subject (like she, he, we, they).
Examples: I like the color blue. My husband and I went to the movies.
"Me" is used as an object (like her, him, us, them).
Examples: Something happened to me today. My sister loves that picture of Kelly and me.
"Myself" is a reflexive pronoun, which means you use it when you're the object of your own action.
Example: I see myself winning the tournament.
The only other correct usage of myself is for emphasis: I myself love Bruce Springsteen's latest album.
