No man is good enough to be another's master

Gardeners know the best dirt

A visitor to a garden sees the successes, usually. The gardener remembers mistakes and losses, some for a long time, and imagines the garden in a year, and in an unimaginable future.

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

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.
