" ...the danger of developing a policy of rush, of being gradually more and more obsessed by what one has to do next. In this way one may come to exist as in a prison, and one's life may cease to be one's own. One may take the dog out for a walk at eight o'clock, and meditate the whole time on the fact that one must begin to read at a quarter to nine, and that one must not be late.
And the occasional deliberate breaking of one's programme will not help to mend matters. The evil springs not from persisting without elasticity in what one has attempted, but from originally attempting too much, from filling one's programme till it runs over. The only cure is to reconstitute the programme, and to attempt less. "
