Every person must make his or her own path in life. Following in the footsteps of another is, no matter how you look at it, a limitation. We are each born with a certain potential, certain characteristics.
This is something we all agree on, I believe. However having certain people you look up to, admire, is merely a healthy effect of not being too arrogant and egocentric to realize that you are not the center of the universe.
As for me, there's my father's uncle who married into the family. He died just about a year ago. A bright, talented and openminded man, who did not lack a sense of humour. He was a poet, artist and vicar, never afraid to speak his mind.
All in all he is one of the reasons that I, ever since I was a little kid, have longed for the day when I would be an old man. He was just that cool.
Appart from him...hmmm... Rune Andreasson, Don Rosa, JAS and Sven Nordqvist are among my childhood rolemodels, JAS being somewhat more recent and admired mostly for his ability to capture the local flavor (comic-artists, if you know who all of them are, well, either you are swedish or you really know your comics)
Then there are the historical figures I admire, of which Martin Luther and Karl the 11th (King of Sweden, known as "King Blackcloak" or something of the like) are the first that come to mind.
And of course the many authors and scholars I have aquired a certain admiration for, too many to count.
This, however, does not mean that I in any way strive towards becoming these people, as I would merely end up a pathetic shadow of my true potential.
Admiration is a healthy product of my hierarchial mind.
