I'm still not really keen on the "the enemy is I option".
I guess it's in line with the theme of the concept, but it still strikes me as too bleak.
The first option has a more hopeful outlook, continuing on the previous version's idea that the efforts of a single person, no matter how mighty, will always be limited. It highlights the importance of Community and Communication to combat Isolation.
And again, refusing to stretch out your hand to others is hardly the only, or even main, cause of isolation.
How many people are there, desperately reaching for others, just to be refused and ridiculed or scorned for the attempt?
I don't want LQ's to shrine the idea that Isolation always starts with oneself, as if overcoming it was just a matter of trying.
