How many times have you been on the freeway and had someone fly by you at 100 mph then end up two cars ahead of you at the off ramp? What's the point?
If you're trying to achieve, there will be roadblocks. I've had them; everybody has had them. But obstacles don't have to stop you. If you run into a wall, don't turn around and give up. Figure out how to climb it, go through it, or work around it.
I design my shots. I walk the rehearsal as the camera and say 'this is where I want to be... I want this look.
