You aren’t restrained by anyone. If you wanna become a movie director than buy a camera, watch a few tutorials, experiment around and BINGO - be a movie director. If your current job pisses you of and makes you unhappy than have guts and simply quit. Stop moaning around if you think your talent is stuck somewhere it doesn't belong. It’s your decision if you wanna make your talent go somewhere. Don’t wait till people start pushing you. Go for it.
