You were always a bit discontent, dissatisfied with life. Your mother chided you for not knowing when to leave well enough alone. You tried your best to fit in, to live like everyone else seemed to manage to, but...
It was supposed to be "the future." All the wonders mankind had dreamed of had come true. Robotic servants existed to cater to your every whim if you so desired. No one was hungry. Everyone had a place to live, and a place to work. You could live out every fantasy in high fidelity holographic detail. There was nothing dangerous, and everyone knew immortality was just around the corner.
The only thing that wasn't the same old, stale, stifling sameness was space. No one who was "normal" was all that interested in space. Space ships existed, of course. What sort of future wouldn't have space ships? And you could get on a space ship, and take a pleasant cruise that was painstakingly the same environment as could be found in any city or town, and quickly and painlessly travel to another planet, never having to even seen a single star. And once you arrived you could find comfort is how safe and similar that planet was to your own!
And it while you were mulling over your future, your tomorrow and tomorrow and tomorrow...
And then it all came together, in once crystal clear moment. A single event, that caused your true future to click into place.
You were going into space. You were going to be a pirate.
And the trigger for your new life...
[] They called you mad! Laughed at your ideas, and told you to get back to work. Well, you'll show them, you'll show them all! Show them Piracy!
[] If you died today, who would remember you? Who would even want to tell your story? No. When you're done, everyone will know your name! Because Piracy!
[] How no one cares about anything beyond their holo screen. There is injustice in the galaxy and you're going to correct it! With Piracy!
[] This system of oppression was just too much for you. The World Government just giving you things?! Did it even ask if you wanted not to starve to death?! From now on, you'll only own things you properly earn for yourself. Through Piracy!
