I found these two quotes on the same page in a favorite little inspirational book of mine, “Daily Strength for Daily Needs,” Selected by Mary W. Tileslon:

“Of all paths a man could strike into, there is, at any given
moment, a best path for every man; a thing which, here and
now, it were of all things wisest for him to do…His success,
in such case, were complete, his felicity a maximum. This path,
to find this path, and walk in it, is the one thing needful for him.”

Thomas Carlyle

“Every man has his own vocation. There is one direction in which
all space is open to him. He has faculties silently inviting him
thither to endless exertion. He is like a ship in a river; he runs
against obstructions on every side but one; on that side all
obstruction is taken away, and he sweeps serenely over a
deepening channel into an infinite sea.”

Ralph Waldo Emerson
