Direction

Direction and documentary production are not opposite domains and can never be. A director is part of the documentary production as well. The director may make informative/educational work, entertaining movies, animations, thrillers, romance or children movies. The direction is the most important thing.
Hence, direction is a comprehensive term whereas documentary production is a part of the main.

A course in direction cannot be done unless you do a Bachelor's Degree in the film making and production domain. It is made clear merely a certificate course cannot make someone a good editor to claim jobs at the best places.
I shall suggest that when a good job with growing possibilities is there one has to take up the assignment because mass media jobs are the best to do when they come to you. Once the hunt starts, it takes time.

Hi,
Necessary skills required to be a director:
Writing
Even if a director has never written a script in his life, he still needs to understand how one is written. Screenplays have specific three-act structures, and being able to recognize how a script adheres to this structure is an important skill in filmmaking. Often, a director will rewrite a script to put his own stamp on it, whether it is a simple polish for dialogue or a complete overhaul to meet his creative needs. Whatever the reason, doing this will be difficult without the ability to write.
Visual Storytelling
The written word on the scripts page is the start, but ultimately the filmmaker has to translate those words to images. To do this, he must be able to tell a story visually. Many film students start out making silent films. The reason for this is to teach them how to convey the action onscreen without words. The audience should have an idea of what is happening onscreen, even if the characters arent speaking. Dialogue and music will ultimately enhance a film, but cannot save a picture if it is visually confusing.
Communication
Making a film is virtually impossible to do on your own. You have to manage actors, camera operators, sound technicians and editors at minimum. The larger the film, the more moving parts you must manage. Successfully navigating different workers - each with his or her own ideas, methods and egos - requires strong communication skills. You have to successfully convey your vision to each of them to ensure it ends up reflected in the finished film.
Technical Expertise
It's not uncommon for a creative person to have no interest in the technical side of things. This does not work for a filmmaker, however, as his idea of John bursts through the door may be totally different from the director of photographs. You don't need to know every moving part of a camera, a light filter or a boom microphone. However, you do need to know how to frame and light a shot and be able to recognize when sound levels are off. If you don't have the know-how to do these things, the finished product will not be your complete vision.
