Mark and Jay Duplass have really given away the secret sauce in filmmaking...be consistent, on the cheap, & perfection-free. Most important they give everyone a stake in the project:) http://nofilmschool.com/2016/03/7-secrets-duplass-brothers-mark-jay-dupl...
I usually do two 5-10 min short films a year. Could do more, but since I don't want to do everything myself, I usually have to wait for other people to do their bits (post)... somehow ends up taking about 5 months for every project...
