1593-1603 by Shakespeare 
Sonnet 50 

1	How heavy do I journey on the way,
2	When what I seek my weary travel’s end 
3	Doth teach that ease and that repose to say
4	“Thus far the miles are measured from thy friend.”
5	The beast that bears me, tired with my woe,
6	Plods dully on to bear that weight in me,
7	As if by some instinct the wretch did know
8	His rider loved not speed, being made from thee.
9	The bloody spur cannot provoke him on
10	That sometimes anger thrusts into his hide,
11	Which heavily he answers with a groan
12	More sharp to me than spurring to his side#
13	For that same groan doth put this in my mind:
14	My grief lies onward and my joy behind.
