This is pretty raw

Circle of Life

I have two hands and one life. 
I jammed one into a jar of peanut butter 
and noted with pride the lasting impact 
to the Skippy.  The other hand, a symbol 
for decades of rhetorical instruction 
and grading, cannon-balled 
into the university pool.

I like this duet.

But.

I want a different title.  Something specific.  Something that grabs me.  Circle, okay.  Circle of Life ... not so much.  The title didn't make me want to read the poem, and the poem deserves better.

not ignoring this.  Back to it.

I agree with Karen.  You have not thought long enough about the title.  (Too big, too general.)
I'd look at "noted".  I know that's teachery, but how about a verb with human feeling?  smiled?  
L 1:  I'd drop:  and one life.  
The hand cannon-balled?  Is that what you mean?  If so, what does that look like?  
Last 2 lines.  Like in a pool of teachers?  
Yep, I want your meaning, not my imagination. 
Are you saying teaching is your life???  Sorry, I am just full of questions here.

Title seems like a clechet (sp?)...
How about DICATOMY?
I love  these two images... feel the butter... crunchy, too.
And sitting endlessly in the Department meetings knowing  all power stops at DEAN...
I wouldn't change anything about the poem except the title.

Did I clear enough initial clutter to determine what needs to change?

Conclusion of Retirement Speech
 
I have one life measured by two hands.
I jam one into a jar of peanut butter
 
and note with pride the lasting impact
outlined in Skippy.  The other hand, a symbol
 
for decades of instruction and grading,
cannonballs into the university pool.

And I like the couplets!  Good addition.  Title is wonderful!  
This is much clearer. 
Makes me think of Mark and his closure.  Ohhhh, we are going to miss him at Lucidity.  You and Carla are going to miss him and Linda every day.  Can you tell how I hate such changes, even though good will come out of it. . . .
