No man is good enough to be another's master.

No man is good enough to be another's master

No man is good enough to govern another man without the other's consent.

Protect, detect, react and deter. For example, firewalls are only of any real use if you master them and take action when you notice something wrong.

The reward of labour is life. Is that not enough?

Let every man be master of his timeTill seven at night.
