We'll stay here as long as we feel we're making progress, ... If we're not making progress, we're not going to stay.

There has been progress in this (so far) and we don't want to have that progress slip away. ... We've been rolling this rock up the hillside and we don't want it to roll all the way back down.

If we're not going to make progress, we're not going to be here,

we didn't make as much progress as we planned.

I can't say really that there has been progress,

We had another long day. We made a little progress but I must say we didn't make enough progress.
