Famous quotes containing the words trail and/or difficulty:
“We sank a foot deep in water and mud at every step, and sometimes up to our knees, and the trail was almost obliterated, being no more than that a musquash leaves in similar places, where he parts the floating sedge. In fact, it probably was a musquash trail in some places.”
—Henry David Thoreau (1817–1862)
“I always say, my motto is “Art for my sake.” If I want to write, I write—and if I don’t want to, I won’t. The difficulty is to find exactly the form one’s passion—work is produced by passion with me ... Mwants to take.”
—D.H. (David Herbert)
