Response to the Second Stanza of Chiasson's "Bicentennial"

In the second stanza of Chiasson's "Bicentennial", the speaker continues building what is to become a high-energy (if not overstimulating) picture in which optimism bursts through even parts that are much less wholesome . The speaker describes what is either the ferris wheel in front of him, or the "small white tee" (the kind in which you put your head to get pied?) that his head is in. He uses this stream of memories to escape from his self-imposed commitments as an adult (e.g., poems, writing). His frustrations over these commitments are centered around how abstract they are, and he desires a sensory experience (which is where desire belongs anyway). In contrast to poems, the attractions at the Bicentennial mentioned hold no "secrets" neither about power nor the dangers they present therein. To the speaker at five years old, they offer only excitement, fun, hope.
I understand the speaker's desire to break away from writing poetry, or at least from the sense of security doing so provides. He wants to open himself to something that both excites and scares him. There is danger in the anticipation, particularly, for whatever he's expecting to happen to his head on the small white tee.

The speaker kind of loses me with the construction of the last three lines of this stanza-"and this is all,/ I am afraid, will move my mind one inch/ off the small white tee where it sits and waits." Can any of you explain this part to me?
