A constant element of enjoyment must be mingled with our studies, so that we think of learning as a game rather than a form of drudgery, for no activity can be continued for long if it does not to some extent afford pleasure to the participant. Desiderius Erasmus
It is generally agreed that no activity can be successfully pursued by an individual who is preoccupied – not rhetoric or liberal studies – since the mind when distracted absorbs nothing deeply, but rejects everything which is, so to speak, crammed into it. Seneca
There is practically no activity that cannot be enhanced or replaced by knitting, if you really want to get obsessive about it. Stephanie Pearl-McPhee
