Important.

It was something Bo Diddley told me. He always carried his own guitar. I said, "There’s a person over there who’ll carry your guitar for you, someone who looks after the equipment." And he said, "No, no, I always carry my own guitar because if I rely on that person and one day they’re not there, suddenly I have a problem." That was an important lesson for me. I try to rely on nobody else but myself, which means not blaming anyone else either.
