As Socrates said, a moral life is one of continuous questioning. It's much better and braver to live with the discomfort of uncertainty than to opt for the certainties of totalitarianism or fundamentalism. Get stuck into ethics. Don't leave it up to religious people and politicians to decide what's right and wrong. Make sure you have your say.
Obedience can be a deadly virtue.
Be prepared to disobey orders you don't agree with. Look at your circle of concern. Ask ethical questions about things that aren't usually connected with morality. They may well be before long. It took me many years to realize that living ethically was not about some unattainable virtuous ideal from which I already felt disqualified at the age of seven.
