When one door closes / shuts, another opens

[Theseus]

When one door shuts, another opens.
Prov. When you lose one opportunity, you often find a different one.

--Jane: I just found out I'm failing two classes. I'll never get into college with grades like this.
-- Jill: Well, maybe you'll find something better than college. When one door shuts, another opens.:)
