Can impatience be virtuous?

Suppose that Linda, Brian’s partner, is on a business trip. Brian cannot wait for her to come home. It would be plausible to construe his attitude as impatience, and claim that it is called for in this type of situation. But if this is indeed the case, then patience is uncalled for. However, it seems that patience cannot be uncalled for, as it is considered a virtue. So goes the common expression, and so attest all of the philosophical analyses of patience in recent decades. Discussing them, I claim that patience is not always the right attitude. Enthusiasm and excitement, which might be impatient, have their own merits. Furthermore, as patience involves not only waiting, but also enduring or persevering, it might also be the case that one endures too much and thus allows vice to flourish. Being truly virtuous has to do with knowing when and how to be patient, but also when and how to be impatient.
