“I’ll do what I can” is a challenge to fate,
And fate must succumb when it’s put to the test;
A heart that is willing to labor and wait
In its tussle with life ever comes out the best.
It puts the blue imps of depression to route;
And makes many difficult problems seem plain,
It mounts over obstacles, dissipates doubt,
And unravels kinks in life’s curious chain.
—Ella Wheeler Wilcox
