The man is a well of creativity; as long as he has something to say, he will always find new ways to say it and sing it. He has always been true to song and performance -- and I would say he continues today at the top of his form. I can write an essay for each of Dylan's songs, if I wanted to. Then I could write one for each live performance of those songs. Incidentally (and very few critics or fans have come to grips with this yet), it is Dylan's work in the 70s, plus his live performances that, even more than his extraordinary and better-known creations of the 1960s, gives him his claim to immortality.
If I tried to tell you what I learned from listening to Dylan, we'd be here for months. The subtleties of Dylan's live performances -- timing, arrangement, voice, attitude -- are at the heart of his achievement as an artist. He was a hero of mine and still is, because his work still reflects the kind of deep-soul courage and integrity and commitment to personal and artistic growth that I've admired him for from the beginning.
