impetuosity

His caution (the use of long and short dashes) and personal pride (tall ‘t’ bars) will help guard against impetuosity.

He was a dark-browed, good-looking youngster of nineteen, greatly resembling his mother, but with ten times her impetuosity.

But glorious as his conduct was, his rash impetuosity more than once seriously compromised Napoleon's plans.

But glorious as was his success, his impetuosity soon brought him into further disgrace.

His impetuosity called forth the expression, “He is a fanatic who will lead us to a precipice.”

In their impetuosity they have rushed into the other extreme, and demand for science more than she can rightly claim.
