There’s a beautiful quote from the BBC series of Dr Who, where in the final moments of his current life, the 12th Doctor (played by Scottish actor Peter Capaldi) makes a passionate and heartfelt speech to his enemy.
“What would you die for?...Who I am is where I stand. Where I stand is where I fall.”
Our values - such as integrity, trust, loyalty - are where we stand. They are the driving force for what we do, or not do.
