Dream Job: Onmyouji 陰陽師

Today at work, it was boring.
And thus, I was thinking about what I want to be when I grow up!



And I thought. I love the occult. I love the concept of spirits and alternate realms. I believe in onmyoudo 陰陽道, and 風水. Naturally, one of my dream jobs would be to become a onmyouji (陰陽師)!

Now I just wonder, how does one get into a field like that?
And is it a modern viable job to earn money?
What qualifications would one need? Maybe there's some sort of test to see if you're skilled enough in manipulating the arcane to achieve various feats....

And no, I didn't just came up with this idea because I watched the movie.
