Since the accident, I've gotten much more efficient at using my time effectively. I was unable to do much for a couple months, and it was terrifying. I also came to understand my mind better as it healed. As a result, I pretty much spend every waking minute that I'm not with my wife productively: consulting, working on my startup, or writing. Most everything else bores me now.

I think I'm probably 90% as smart as before the accident. However, I didn't use but 60% of my time productively before - I now use it much more productively, which results in a major net productivity gain :) I just have to restore sanity to my situation and I'll be much better off.
