It is not enough that we do our best; sometimes we must do what is required.

Continuous effort - not strength or intelligence - is the key to unlocking our potential.

Never give in. Never give in. Never, never, never, never—in nothing, great or small, large or petty—never give in, except to convictions of honour and good sense. Never yield to force. Never yield to the apparently overwhelming might of the enemy.

Never, never, never give in!

If you are going through hell, keep going.

Every day you may make progress. Every step may be fruitful. Yet there will stretch out before you an ever-lengthening, ever-ascending, ever-improving path. You know you will never get to the end of the journey. But this, so far from discouraging, only adds to the joy and glory of the climb.
