Hire your weakness
The concept of writer, producer and director while sounding very nice usually doesn’t work unless you are Orson Wells or Stanley Kubrick.
A wise man, John C Maxwell said “A self made man hasn’t made much at all”
So hire, or find, your weakness. If you’re good at directing, or think you are, then get someone on board who is good at producing. If you can’t write, then don’t! Get someone who can. You get the idea.
By hiring your weakness, you will create a strong team.
