The troubled actress - who has been in and out of jail throughout the year after breaking her probation in relation to a 2007 DUI (driving under the influence) conviction - blames her past actions on "stubbornness", but admitted she holds herself "accountable" for what she has done.
She said: "Ultimately we are each responsible for ourselves and for our actions. Looking back, I probably would have listened to and taken more advice from the people whom I admire and would have followed through with it more.
"My stubbornness at 18 and 19 years old got in the way. During the past five years, I`ve learned that time flies faster than you think, and because you only live once you have to learnfrom your mistakes, live your dreams and be accountable."
The 25-year-old star also thinks "sex and sexuality are a part of nature", and she believes being confident about her body can help her along in such a "male-dominated world".
Speaking in an interview with Playboy magazine, for which she posed naked in a Marilyn Monroe-inspired shoot, Lindsay added: "Sex and sexuality are a part of nature, and I go along with nature. Knowing yourself and your body is so important because it gives you confidence, and in life, women need confidence.
"It`s a very male-dominated world to begin with, so knowing yourself and being comfortable with your body is an important thing for me as a woman."
