People of great character are so often multi-talented, like
Reagan & Condi Rice, don't you think?
People who confuse talent with character seem to be the narcissistic
types you and Wells describe.
Some exceptions I admire are
Mel Gibson, Jimmy Stewart, Robert Duvall, Jean Stapleton, Ginger Rogers and many other principled stars and leaders.
I personally know of no great artistic talent of Condi Rice.
Gibson is a bit of a flake. He's not even as remotely conservative as some like to believe.
Stewart is truly the exception, as I suspect is Tom Hanks. There are always a few like that, but they're the exception not the rule.
I know diddley squat about Jean Stapleton or Ginger Rogers, so I won't say a word.
Duvall is a genuine actor, with all the baggage that it implies. He's about as weird as Depp living in the woods of France, only Duvall long since retreated to Argentina.
I could give examples all of day of artistic talents being truly weird individuals, and often broken individuals as a result:
Van Gogh, Hemingway, Dorthy Parker, Orson Wells, Marlon Brando, Robert Dinero, Robert Dinero (anyone that weird gets two mentions), Edgar Alan Poe, Edgar Alan Poe, Frida Kahlo, Dora Carrington, Mozart, Mozart, Beethoven, Stevie Ray Vaughan, Jimi Hendrix, Janice Joplin, Henrty Miller, Tennesee Williams, Oscar Wilde, D.H. Lawrence, Thoreau, Emerson, Judy Garland, Pavorati, Richard Burton, Joan Crawford, Bette Davis, and anyone ever named Barrymore.
That's just a quick list off the top of my head!!
