One nugget of wisdom I try to pass along to younger designers:

Your job is to inform judgment, not to impose it.

Paradoxically, judgment becomes less arrogant as it matures, improves and becomes genuinely superior.

I learned this lesson the hardest way. I’ll be paying down my debt for the rest of my life.

Anaximander:

Beings must pay penance
and be judged for their injustices,
in accordance with the ordinance of time.
