Famous quotes containing the words trail and/or difficulty:
“And Change with hurried hand has swept these scenes:
The woods have fallen, across the meadow-lot
The hunter’s trail and trap-path is forgot,
And fire has drunk the swamps of evergreens;
Yet for a moment let my fancy plant
These autumn hills again: the wild dove’s haunt,
The wild deer’s walk: in golden umbrage shut,”
—Frederick Goddard Tuckerman (1821–1873)
“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)
