A poem I liked a lot, from the back of a box of Ginseng tea.

Determination

by Ella Wheeler Wilcox
There is no chance.
  no destiny,
  no fate,
Can circumvent or hinder
  or control
The firm resolve of a 
  determined soul.
Gifts count for nothing;
  will alone is great;
All things give way before it,
  soon or late.
What obstical can stay the
  mighty force
of the sea-seeking river in its
  course,
Or cause the ascending orb of
  day to wait?
Each well-born soul must win
  what it deserves.
Let the fool prate of luck.
The fortunate is he whose
  earnest purpose never swerves,
Whose slightest action
  or inaction serves
The one great aim.
Why, even Death stands still,
  and waits an hour sometimes
for such a will.
