Awaiting something that is justly deserved, is the same as denying it for however long it takes to achieve it. It is the same as; "Justice delayed is justice denied". William Ewart Gladstone

This is Martin Luther King's quote. You should fight for your right because you may have only one chance to win or get what you want. However, an unjustifiable delay may cause you loss. You won't enjoy your right if you delay it.
