Still, if you will not fight for the right when you can easily win without bloodshed; if you will not fight when your victory will be sure and not too costly; you may come to the moment when you will have to fight with all the odds against you and only a precarious chance of survival. There may even be a worse case. You may have to fight when there is no hope of victory, because it is better to perish than to live as slaves.  — The Second World War, Volume I : The Gathering Storm (1948)

My Take – Putting off something that’s unpleasant, be it a war or confronting a personal problem, when you have a good chance of success is foolish.  Life has a way of making those things we put off much worse as time goes by.  Time does not heal all wounds; most of them just start to fester unless attended to properly.
