If you hesitate doing something, it might not be important to you.
(Of course, we often hesitate with things that are in fact important to us, because we're afraid to fail. So this proverb is more meant/used as a motivation for someone hesitating, or even as a teasing to get someone into action)

He hesitated to tell Eytukan the news.

The hunter hesitates and the hexapede escapes.
(Proverbial expression. Cf.: “He who hesitates is lost.”)
