what i mean by drawn to what you lack, is usually the polar opposite, eg someone who is of the air would have great imagination and ideas and quite happy to have their head always in the clouds, but because of that, they lack the earth which they need to make sure they dont get into any bad situations or downfalls, being money, love, social situations, time-keeping, etc.
i am drawn to fire, because it is powerful and i corrispond it to a more destructive force, as opposed to water, which i see as calm. Although all elements can be destructive, i only see fire as the most destructive force. this balances with my calmer (or so called calmer) more watchful side.
