No, but I will one day. I consider entrepreneurship a basic life skill today, even if I do work for someone else. At this point, I'm just accumulating skills and resources to being my own boss. It also helps to find an all-consuming passion, which Aspies are great at. For me, it's maps and geography, and I've taken a renewed interest in sharpening my geography and cartography skills.
I consider myself a proactive employee, and always on the hunt for ways to help my business. There are employers who do not value this. That's a shame, because proactive employees are the ones who add the greatest value, even if they screw up a few times. Enough employers (including the one I'm with now) expect proactivity that I don't think it's an unreasonable demand.
