It's the things against which we feel powerless that really weigh us down--authority, weather, circumstance. The answer, of course, is time, which is the only thing that can shift any of the above. But time isn't the most acquiescent of partners, and the only thing our constant pushing and griping and pining accomplishes is one more day of exhaustion, one more day of moody cheerlessness.
But I think time (and, if you want to go there, fate/karma/divine will) would probably rather trundle along without our so-called help. I think time has it all in hand and probably, hopefully, knows what's best for us. Not that it makes it any easier--giving in to another entity that 'knows best' rarely does. But it does lift a burden, at least for a while. And that, in itself, might be enough for now.
