Exploring isn't a disease, its a natural progression, an enhancement, an evolution from a lesser form.
Normal pilots are bound to human space. Fear keeps them near the cave mouth of their stations and planets, from whence they can hunt in groups for the meager resources they need to survive, and to which they can retreat when fear of the dark and of the unknown becomes so great that they need to hide. They are the ones who sail close to the shore, content to ply their trade in a small spit of sea, afraid of the ocean and riches beyond, unaware even, of just how vast the ocean even is. For them a quick step around the corner is a marathon event, to be planned for, considered, and never undertaken lightly.
We explorers, on the other hand, had the courage to leave the nest. We had the curiosity to want to reach the horizon and look out to see what we might find beyond it. When our ships cry out for fuel, we don't need to visit a station for a top up, we seek out a star and leech it of it's promethean flames to allow us to power onward. We dont need to live in the dirt anymore, and find our home in the open skies. We hear the songs of the stars, and we are no longer afraid of the voices in witchspace.
Whilst lesser men fight and struggle over the meager resources of a few tired systems, seeking dominion over one another, we continue on, in peace, finding all the things we need in all the space around us.
When you hear the call of shiny things, don't lament it, give in to the temptation, relish your curiosity, because whilst you travel the spaces between the stars, lesser men still hide in the shadows under the tree's they only just stopped living in.
