LLTM: "The Choice"

I read the poem, "The Choice" by William Yeats in the Leading Lives That Matter book.  The poem, although short, has much to say about the decisions we make as humans.  We can either choose to work, meaning make a career for ourselves, be known in that career, and have an alright or decent life that way, or we can choose the 'perfection of the life', meaning to live socially, give ourselves the ability to survive through others and most likely off of others.

But in this poem, Yeats says if we should choose wrong, "the day's vanity, the night's remorse", which, in my opinion, seems to say that we will have pleasure to the public eye, but nothing more.  For example, during the day, one will live lavishly, expensively, and arrive in a limo.  But as night falls, the lavish decorations begin to deteriorate, the expensive catering turns into take out, and the limo turns into a taxi.

A line that confused me was when he said, "And if it take the second must refuse/ A heavenly mansion, raging in the dark."  I'm still not certain what the first part means, but after reading it a few times, I realized that I liked the second line because it seemed to suggest that the truth came out at night.  It seemed to say that while people will see your house during the day, they will pay no attention to it as darkness comes because there will be no reason to.  Like many women wear make-up during the day and people notice, once the party is over and they have returned home, there isn't a point to keep it on anymore, so most of those women take it off, revealing their true selves.

But then the book asked an interesting question- Is the quest for perfection (or even for highly distinguished accomplishment) essential for a life of significance?  And it seems to me that the answer is no.  I feel that if I'm doing something I love, with people that I care about and who care about me, and I am able to survive on a lifestyle that isn't poverty, but isn't overly prosperous or lavish, I feel that then I'm living a life of significance.  If I feel that I'm either making, or can make, a difference in someone's life, just by doing what I do on a daily basis, then I feel I'm living a life of significance, and therefore, I have achieved the 'supreme good'.
