I just assumed that the inventor of Shift+F7 was the inventor of the Word Thesaurus. Weird how you didn't...

Since I've been silly, I'll go ahead and critique seriously. This could be a fine poem, honestly. I would, however:
- drop "Tenuously" from the first stanza.
- reword the second and third stanzas so they're not so overfull of adjective phrases.
- drop "the" from before "past words"
- Actually, make the second stanza something like:
I perch on a tall ladder
stacking words on past words
high as play blocks
... and so on.
- If you must include "teetering precariously", change it to something totally different or drop it entirely. Also, drop "One more record" and "Ignoring jeers and vain praise".

The first line and the last three are really quite good.

A lot of the focus of this poem seems wasted on the struggle-despite-hardship-and-persecution part. Once again, you've neglected to include a part about how you could be totally nuts and musguided. I think that part's a necessity for any poem, even if it's only lip service. Why not throw in a Babylon reference or something so people (including yourself) don't think you're just cocky? I know a great place for one (hint: instead of stanza three.) Anyway, give it some thought. Sorry for being facetious before. I really rather liked this one.

Correction: "Correction"

word. no, ha! the end of the first line in s-2 I don't think you need it. I used to love block when I was little. still am. still do. Basement full o legos.
