Here's the first verse:
People come, and people goMovin' fast and movin' slowI'm in a crowd, yet I'm all aloneThe road is long, the road is roughI do believe I've had enoughI'm gonna turn around, head for home
The first two lines rhyme, but the third doesn't continue this; just like being "alone," it stands apart from the other two. Similarly, the fourth and fifth lines rhyme, but the sixth doesn't follow suit, and this diversion matches the "turn[ing] around" in the lyrics there.
There's an-other instance of this significant structure in the second half of the second verse:
I've played a game that couldn't lastAnd now some mem'ries from the pastHave turned my thoughts around a different way
The first two lines establish a pattern that the third breaks from, and this matches the meaning of "turn[ing] my thoughts around a different way."
