It reminded me of our presentation at PhotoCamp, where a lot of people listened to a few of us ramble on about DSLR filmmaking and photography. I find it astonishing that so many people have a psychological barrier to beginning creative pursuits.
If you want to be a filmmaker, make a film. If you want to be a photographer, make photographs. If you want to make video games, make video games. If you want to write a novel, write. The key is to identify what you need to reach your goal, and do it. Things like training, tools, software, hardware, materials, time. You do NOT need permission.
And if you still don't believe me, fine. I hereby grant you permission to make and do anything you want. Problem solved.
