“The stars can only be seen at night.” or “The stars only shine at night.” This is to be a slogan for my personal brand. It essentially means that it is during dark times that heroes arise. It’s kind of a less childish version of “it’s your time to shine”, in that it is also meant to be read as a sort of call to action. I’d like it to be a short sentence, four or five words if possible. If that’s not possible, it is what it is I suppose. I would also be interested in any existing Latin phrases or proverbs that have a similar meaning, if indeed there are any, whether they make reference to the stars or not.
