We’ll have to make sacrifices…
We prefer not to say this kind of sentence because:
The « a little » in this formulation suggests the worst and the « much » … Now, we can get out of the positive situation that imposes savings or restrictions.
It is better to say:
« Given the resources and resources available, we will have to do better with less, so be more creative »
We can also add a call to good wishes and suggestions in stride.
