Project managers are not alone
A project should not be composed a leader on top and everybody else below. Actually, that's a very good way to fail. Your team is there for the project, and so are you. Why not work together?
You need to work together.
Be with your team. Spend time with them. Take the time to explain what's going on in the project. Listen.
When problems arise (they always arise), your team's unique perspective may be the key to solving it. Budget problems? Maybe one of your developers knows a less-expensive tool that does the job just as well. Schedule problem? Your QA specialist may have a few tricks up her sleeve to speed up the testing phase.
Project managers are not superheroes. We can't expect to fix everything on our own. That's why there are project teams.
The project can't succeed without the team, but it can succeed despite the project manager.
