Never care more about someone else's project than they do. (A more positive version is "Your job is to do your job, not someone else's job.")

This isn't your project - it's your company's project. It will get done according to the resources that the company has provided, resources which are largely outside your control OR responsibility.

If this project is late and/or crap, that's on them. They own the consequences of their decisions, good or bad, not you.
