Robert Lee Frost has got to be my favorite poet. I'm also drawn towards Shelley, but Frost's poetry is simple, beautiful, and perfect for the lone wanderer. The fellow has 4 Pulitzer prizes in poetry. Here is a favorite from my school days. I read it, probably, somewhere around middle school. I didn't know it would come back to me so perfectly suited. It always does feel like I have miles to go before I sleep.
"The woods are lovely, dark, and deep,
But I have promises to keep,
And miles to go before I sleep,
And miles to go before I sleep."
Robert Frost - Stopping By The Woods On A Snowy Evening
