Svengali: One who manipulates or controls another by some mesmeric or sinister influence; especially a coach, mentor or industry mogul.
During my life and career, I have encountered Svengali types more often than one would expect. I get an idea and have a vision of the idea and under the guise of helping me realize my vision, they try to steer me in a direction that they say is the best for me. (Not really for them.) Or they try to sabotage my work by giving me bad advice behind the mask of being a friend. Much like the character Salieri, in the movie Amadeus.
This has happened, to me, in the recording studio, when I was making music videos and in my private life. If you have something that is good, they will be jealous of you, You have, most likely run into them, too. They will fill you with lies about friends they say are your enemies, and enemies they say are your friends.
They are charming and supportive at first and then, once they have gained your trust, they will turn on you and show their true colors.
Remember! Always go with your gut. If someone tries to derail your vision, get rid of them. You are the artist. You are the captain of your ship. You must discipline yourself to stay on your original course.
This is difficult to write about. I am not sure I am getting my point across. I am flying by the seat of my pants and believe this is how I should, and always have, felt.
Remember! Just because you're paranoid doesn't mean people aren't out to get you.
