The 26-year-old actress - who has starred in the likes of 'Twilight', 'Equals' and 'Snow White and the Huntsman' - says it is "rare" that something turns out exactly as she had hoped.
Asked how she would describe herself as a director, she said: "I'm a pretty obsessive person, which is I think entirely necessary. You have to be a little crazy to put yourself through something like that and actually make it happen. I was probably a little bit more controlling than I thought I would have been. My favourite thing in the world is when it feels like something starts to get up and walk itself.
"When something's really good, and it's rare - honestly I've made a million bad movies. Not bad, it's just like sometimes they don't come together in a way that feels miraculous and when they do, it genuinely feels like something is floating and you're all sort of blowing on it to keep it up and it's like, that fully happened. It's so cliché, it feels like super pretentious to say this, but you genuinely feel like this vessel and you're like, 'That was sick, I don't even know what just happened,' and it's just f***ing real."
And the brunette beauty - who has stepped behind the camera for short film 'Come Swim' - issued some advice for other young women wanting to follow in her footsteps.
She added to Refinery29: "Anyone I've met that's doing things for themselves and really compelled to do so, you can't get in their way. There's just no stopping them and I would say, trust that.
"There are people that just desperately see things and just want to explain the beauty of something. If you have that, you f***ing have it. It's the worst advice ever, but just believe in desire. It's the worst f***ing feeling in the world just to want something and deprive yourself of it. Just f***ing do it."
