one's discretion

Years, of discretion, mature years; At discretion, according to one's own judgment; Be at one's discretion, to be completely under another person's power or control; Surrender at discretion, to surrender unconditionally, that is, to another's discretion.

For one's interest in life is stronger, God knows how much stronger, than one's discretion, and one's love of life than one's wisdom, and one's curiosity in life than one's ability to record it.
