When I was one and thirty.....? HELP?

Question:

When I was one and thirty.....? HELP?

I can't find this poem. I heard it when I was younger, and loved the rhythm of it. Unfortunately, only one line seems to have stuck--
"When I was one and thirty, I heard (someone?) say, give crowns and pounds and (I think) guinea but not your heart away."

I've looked it up on my own online, but I'm not getting anything.

10 points to the first person who can give me an accurate link to the poem.

A. E. Housman (1859–1936). A Shropshire Lad. 1896.

XIII. When I was one-and-twenty

WHEN I was one-and-twenty
I heard a wise man say,
??Give crowns and pounds and guineas
But not your heart away;

Give pearls away and rubies
But keep your fancy free.??
But I was one-and-twenty,
No use to talk to me.

When I was one-and-twenty
I heard him say again,
??The heart out of the bosom
Was never given in vain;
??Tis paid with sighs a plenty
And sold for endless rue.??
And I am two-and-twenty,
And oh, ??tis true, ??tis true.
