Better a skilled farmer than a foolish philosopher.
Quote:'First of all by realising that a teacher without his students is like a an egg without the chicken. It will never be hatched (if it can be layed at all).'
I don't think your teacher/chicken, student/egg analogy works. Chickens lay eggs. Teachers should not "lay" students even in the vulgar sense of "have intercourse with".
One could say that both your metaphorical chicken and your metaphor have laid an egg. The past tense of "lay" is "laid", not "layed"
A teacher without students is like a hen deprived of her brood.
A teacher without students is like a sheepdog without a flock.
A teacher without students is like a terrier without rats.
