The "Freaky Friday" actress said she always knew turning 30 will be a defining moment in her life, reported Female First.
"When I turned 30 I always aspired for this, I always said when I turn 30 that will be the defining moment of what I want to do. I found a lot of solace I reached inside and what my intentions were in the world. Taking control of my life," Lohan said.
The actress, who began her acting career at the age of 10 with soap opera "Another World," said she believes living in Los Angeles as a teenager contributed to her troubled past as she "surrounded" herself with "the wrong people".
"I don't think it was ever turning to anything, it (drink) was very accessible when I was 16, 17, 18, 19. I had been working so much and surrounded myself with the wrong people going out drinking was the wrong thing to do. I didn't listen to anyone.
