Art can be an extremely personal thing– the manifestation of an idea that originated inside of the deepest part of your psyche.
I’ve had the extreme pleasure of working on on film and video projects for the past 20 years, and I understand the importance of collaboration. As much as I want to write, shoot, direct, and edit (and I have on several projects)– it’s just not practical to think one person can be successful in all of these roles (Although we can all find an example to prove me wrong: Charlie Chaplin, etc). And at the end of the day, it’s just not necessary.
If you surround yourself with competent contributors who you trust to pull their own weight on a project, you have more energy to hone-in and focus on specific portions of the project. More importantly, when you lean on others to help produce a piece of art, the end result is an amalgamation of ideas and input from various perspectives.
