Thomas Fuller

Zeal without knowledge is fire without light.

A good garden may have some weeds.

The fool wanders, a wise man travels.

So we strive for perfection in the areas in which we can control, and that isn't necessarily what provides contentment and joy for ourselves and, more importantly, for our children.

Justice consists in doing no injury to men; decency in giving them no offense.

If I can add, say, 10 great new violin concertos to the repertoire before I'm done, that will be truly exciting.
