If I may post my opinion about this song, pls.
First I must say that, is so difficult to read such a wird(positive way) mind of maybe Bono?
But I triyed.
So in my opinion he is talking about the weakness of Humanity, which every day,hour, minute....is repeating. And we accept that, like a normal think, like a player that knows is will loose. So we go every year, through the same fearness, like the seasons and the leafs, and we get used so we dont see that anymore. But then, maybe somebody does not accept all this, and he says that is so normal and obvious to be so loosers that even a dog street knows it. So there is always somebody to question if we can be different than the logic? Because, we all know that life is heavy, but also a friend, like a sailor knows about the double face of the sea, and like a shipwrecked once is found loose his mystery, but not his value. Then maybe, we have too many institutions telling to us what to do, but they cover the real voice of the captain(Good). Then Bono, says that i tryied it all, but we dont have to give up, because we know how to deal with it, like the sea knows where the rocks are. We just have to accept the sins and mistakes, because we all know where to find back the real meaning of the life, so be less arrogant, unsicure, more open for mistakes. But he ends saying that we are not so full to do that.
