On Memory Alpha, http://en.memory-alpha.org/wiki/The_Inner_Light_(episode)Memory Alpha a writer and producer of TNG (although I'm not sure of his involvement, if any, with this particular episode), Ronald D. Moore,Moore; Senior Writer and Producer of the episode is quoted as saying:
"I've always felt that the experience in "Inner Light" would've been the most profound experience in Picard's life and changed him irrevocably. However, that wasn't our intention when we were creating the episode. We were after a good hour of TV, and the larger implications of how this would really screw somebody up didn't hit home with us until later (that's sometimes a danger in TV – you're so focused on just getting the show produced every week that sometimes you suffer from the "can't see the forest for the trees" syndrome). We never intended the show to completely upend his character and force a radical change in the series, so we contented ourselves with a single follow-up in "Lessons"."
