You are not your clone, by virtue of the fact that your consciousness is different from his.

Agreed. It still would be somewhat irritating tough, to know someone in pain/pieces, who - until a second ago - was just like me. Mainly because from a third point of view it doesn't matter who of us two bites the dust, a second ago we were completely interchangeable and both wouldn't have noticed had we switched our places.
So the corrected statement would be: Every single effort made by my clones and/or me to try and make our lives take a turn for the better or worse is futile.
