If you can't look him straight in the eye

Following is the poem that Chuck Hagel, Nebraska's senior U.S. Senator read out in his Farewell to the U.S. Senate on 2nd October, 2008. The poem's actual author for some is unknown, but this site claims that it's Peter "Dale" Wimbrow Sr. Anyways, it's so perfectly written that none can just ignore it; yet, we can only wish..

When you get what you want in your struggle for self

And the world makes you king for a day,

Just go to the mirror and look at yourself

And see what that man has to say.

For it isn't your father or mother or wife

Whose judgment upon you must pass.

The fellow whose verdict counts most in your life

Is the one staring back from the glass.

You may be like Jack Horner and chisel a plum

And think you're a wonderful guy.

But the man in the glass says you're only a bum

If you can't look him straight in the eye.

He's the fellow to please--never mind all the rest,

For he's with you clear to the end.

And you've passed your most dangerous, difficult test

If the man in the glass is your friend.

You may fool the whole world down the pathway of years

And get pats on the back as you pass.

But your final reward will be heartache and tears

If you've cheated the man in the glass.
