Insecurity is a waste of time.

No one is ever a waste of time if you learn something from the experience. But if you consider people a waste of time well you are simply a waste of my time.

Careers very rarely are a waste of time; jobs usually are.

I'm never sick. Why get sick? It's a waste of time.

My tears of love are a waste of time if I turn away.
