There's an expression I like that goes, "stop throwing good money after bad".

Like so many other expressions, it's grammatically weird, and you wouldn't say out of the context of the expression, but I love it.

To 'stop throwing/not throw good money after bad', means, in a way, cutting your losses.

This is what Apple did, for example, after spending billions and over a decade developing the Apple car.

They decided/realised it was gonna going to work - financially, commercially, both, whatever - and stopped throwing good money after bad, which they clearly redirected to things like Apple Intelligence.

Why am I saying this?

Because I've so far spent around $90 on a trip I'm probably not going to on.

It was my mistake, so many things I'd miscalculated, but now I'm thinking: should I go ahead and spend even more money on a trip that's going to be complicated for me, or should I just cut my losses, stop throwing good money after bad and accept I've lost $90?

I think I know what I'm going to do.
