Don't Micromanage, Get Organized
One of the reasons that crime families like the Corleones become so successful is due to the organization; not just of each task and project, which is orchestrated with supreme timing and detail, but even by being organized as a business. The Mafia structure is inherent to any project's success.
When put in charge of a project, it's all too tempting to micromanage, but by establishing some kind of organization structure, you can trust more in your team. Micromanaging will leave you exhausted and your team with low morale as they think you don't trust in them and their abilities.
You may choose not to publish your PM organization chart, but have it in mind and make sure your team members are aware of their roles. For example, if you have several computer programmers on your team, it makes sense to have one of them the head programmer (capo), then you can go to that one person if you need an answer on something as well as trusting in them to help the others (soldiers) should they need it.
If you have a sizable team or project to manage, then you might also consider appointing someone your "underboss." This becomes particularly valuable as not only do you have an ally, you have someone who is able to take over the project should you fall ill, for example.
