Clinical Trials

The child of trial, to mortality
And all its changeful influences given;
On the green earth decreed to move and die,
And yet by such a fate prepared for heaven.

'Tis a lesson you should heed,
Try, try, try again.
If at first you don't succeed,
Try, try, try again.

But noble souls, through dust and heat,
Rise from disaster and defeat
The stronger.
