"There are always reasons for people's behaviour, and it's easy just to dismiss them and assume that we already know their story, especially if they're no good at showing their emotions. Life gives you all these knocks, it's so easy to form a shell to protect yourself. I've done it myself."

It is essential... that discipline should not be practised like a rule imposed on oneself from the outside, but that it becomes an expression of one's own will; that it is felt as pleasant, and that one slowly accustoms oneself to a kind of behaviour which one would eventually miss, if one stopped practising it.
