It's a Good Life If You Don't Weaken

To me, this song is about individuality in a relationship.

When the colour of the night and all the smoke for one life

This line just reminds me of standing by yourself, out in the country side, at the dusk of a winter´s day. You know when you turn around to go back to the city, that you´ll have to deal with friends and family and work and life, but for now, you are the only life.

gives way to shaky movements, improvisational skills, a forest of whispering speakers

When you go back to ´life´, you find yourself woefully unprepared. So you fake it, just trying to do the best that you can. I think the forest of whispering speakers are those little voices you hear around you. Your friends and family, who think they know what you should do, your intuition, the voice of God.

let's swear that we will get with the times, in a current health to stay let's get friendship right get life day-to-day

I think these lines deal with a relationship. It´s like ´Things aren´t perfect, and I don´t know what the hell I´m doing, but I just want a simple, strong relationship with someone I love. Let´s be healthy, let´s be friends again, let´s just live life day to day without worrying about the future and all those things that don´t really matter.

in the forget-yer-skates dream full of countervailing woes

I think this once again refers to the sense of inadequacy. You´ve shown up at the rink without your skates. Therefore, you can´t play in the game. I think this might refer to a break in the relationship. And I think countervailing woes is sort of the idea that, on one hand, you really want to get on the ice. But on the other hand, it´s overwhelming you, and you´re glad to be able to sit this one out.

in diverse-as-ever scenes proceeding on a need-to-know

I think this line is just going with the flow of life. Go on a need to know basis.

in a face so full of meaning as to almost make it glow

This refers to a partner, that feels some strong emotion.

O' for a good life, we just might have to weaken

and find somewhere to go go somewhere we're needed find somewhere to grow grow somewhere were needed.

To me, those lines mean that to really live life, and feel good, you need to weaken. To let down those defenses, and put yourself in a space where you can grow. In the sense of the relationship, I think it means two people finding their own separate paths, because they were stifling each other. Growing up and growing apart.
