Intuition is the key to everything, in painting, filmmaking, business - everything. I think you could have an intellectual ability, but if you can sharpen your intuition, which they say is emotion and intellect joining together, then a knowingness occurs.
When I was a kid, there was no collaboration; it's you with a camera bossing your friends around. But as an adult, filmmaking is all about appreciating the talents of the people you surround yourself with and knowing you could never have made any of these films by yourself.
Pick up a camera. Shoot something. No matter how small, no matter how cheesy, no matter whether your friends and your sister star in it. Put your name on it as director. Now you're a director. Everything after that you're just negotiating your budget and your fee.
