I'm not sure why it seems inroads are so temporary, so susceptible to minor disturbances. Maybe some of us are just steadier on our feet than others. Maybe some of us feel the tremors long before crisis point. I don't know, but whatever the case, I've never had that skill, though not for lack of trying, not for lack of determined perspective-shifting.
There are some things lost impossible to return. Once, I suppose I thought I'd have great adventures. I thought I'd have love and art and easy joy. I think we forget how hard it all is until we remember. And then we wonder how we got so strong in the first place.
