We must be confident that there is still more ‘life’ to be ‘lived’ and yet more heights to be scaled. The tragedy of middle age is that, so often, men and women cease to press ‘towards the goal of their high calling’. They cease learning, cease growing; they give up and resign from life. As wisdom dawns with age, we begin to measure our experiences not by what life gives to us, not by the things withheld from us, but by their power to help us to grow in spiritual wisdom.

Evelyn Sturge, 1949
