Luck ...

He worked by day And toiled by night.
He gave up play And some delight.
Dry books he read, New things to learn.
And forged ahead, Success to earn.
He plodded on with Faith and pluck;
And when he won, they called it luck …

A nice little sonnet by an anonymous writer ... I am sure at some point, all of us have been at the receiving end of this :)

A nice addendum in the comments section by Neo -

One was asked- "Do you believe in luck?"and he replied -" How else do you justify your rival's success!!!!!
