I think it's perfectly fine to want to be like someone, but wanting to actually be that person? Seems a bit depressing to me.
There are 3 people I would be honored to some day be compared to, Bob Dylan, Bobby Kennedy and John Lennon. I'm not musically inclined at all, but Lennon and Dylan both took an amazing common sense approach to political and social issues that would work wonders if it were used more often. I also believe that Bobby Kennedy would have been one of our best presidents had he lived to win the election.
