Substitute to Don't give up...

Basically, I'm planning to add this on the epilogue of What Happens. I want a phrase that mirrors Ash's "Don't give up until it's over" line, but don't want it to be an authentic ripoff.
So far all of the variations I came up with had been used.

Post your suggestions here, and I'll use the one I like best. The author and the forum will get a shout-out.

Why do you want to change it? It has become something like the trademark of AmourShipping. I suggest you hold it as is.

It's not fir Ash to say. Someone else will.

I'll send you a PM. I think I know what you are getting at.
