Who Am I?

[savannah]

I scribble this question again and again


"Again and again" says It, but says it too much. Let people assume the urgency.

I agree, this needs to be changed. Should I just take out the "again and again"?


in my diary, blunt pencil and a fistful of doubt,



You could arrange the fist and its doubt with a unique concept. Start with eliminating "of", and work from there.

Ok, I will try to work on this. I agree fistful is not very original.

hoping to find a mirror in a bed of words.

I long to be a signature, but morph into a sponge,
crouching in the shadows of others, 


The mirror, the other and the bed. The sponge. Shadows. 
There are potent symbols here; all they need is a little arranging and conceptual framing. Stronger cognitive grammar and statement.
The statement, the living force, being the signature. The signature is your double here, so make your double strong. And consider the destiny of a strong poem successfully portraying itself as weak. How far are you willing to go with that?

Could you explain what cognitive grammar is? Also, by "the destiny of a strong poem successfully portraying itself as weak", did you mean this is a poem where the poet aims to be stronger, but the poem itself is weak? Sorry maybe I did not completely follow.

for a drop of greatness.
Give me your metaphors that glow like comets,
lighting up an audience.
Throw me a word of praise I can wear like an epithet.

I am a castle of dreams, slave to failure,
a believer in ladders to zeniths from rock bottom.
Every so often, a broken rung scrapes against my skin,
sands the edges of a person still forming,
and the conundrum in my heart grows,
in search of a word, an adjective
for those growing blank spaces.

Perhaps, when I've collected enough words,
I would be everything.


I'll come back in a few minutes.
