Also realizing that a lot of times you don't need to iron something at all. Fold it nicely, or hang it up to dry without creases and you'd be amazed at how good it looks without ironing. Short of formal work clothes, I don't have anything that needs ironing.
My idea years ago, if human shaped and sized balloons were easily available, was to put clothes on one, then inflate it until it gently keeps clothes tight, then wait for them to dry. I could never test it however.
