"I feel great!" Lohan, who is celebrating "in Greece with family and friends," reveals in an email interview with Vanity Fair. "Age is only a number, right? I have learned a lot over time. I am in a wonderful place in life and look forward to the near and far future and projects that I am working on."
One of those exciting projects she's referring to is writing a book, where she hopes to share her stories about growing up in the spotlight.
"I am very excited to share my personal experiences in life and how to overcome obstacles," she says. "I hope that my words will connect with those who need some guidance when [or] if they are in a tough place. I am grateful that I have a voice, which I can now feel comfortable using as a platform to let people know that we all have ups and downs in life, and we can all come up from the downs if we get in touch with our inner self and spiritual side."
In addition to writing, Lohan -- who is engaged to Russian business heir Egor Tarabasov -- also hopes to make more films, start a charity and work with children over the next 10 years. Another goal? "Maybe having some of my own [kids] soon -- after I get some movies done, first," she adds.
ET confirmed in April that Tarabasov, 23, had popped the question with a massive emerald sparkler after dating Lohan for less than a year. Ever since the two became engaged, the redheaded beauty has had a seemingly permanent smile on her face. When VF asked what brings her the most joy in her life right now, we weren't surprised by her answer.
"Travel, experience, sharing my love with someone special, meditation, being happy with good people around me, [and] spending time with my family," she gushes.
Lohan also reflects on her memorable moments over the years, telling the mag that she's most proud of "being strong and allowing myself to accept my faults, and with that, being the person I am today."
As for regrets? "I wouldn't call things regrets, per se," she confesses, addressing some of her darker periods, which included a few run-ins with the law and a battle with alcohol addiction. "I can't turn back time. But if I could, I would have listened more to my mother [Dina] and gone back home to New York City earlier in life and chosen my friends more wisely."
In conclusion, her best advice for women approaching their 30s is to "just, be happy and take care of yourself! [Don't] freak out. Embrace it."
Back in April, ET caught up with Lohan's father, Michael, who gave his daughter's fiancé the ultimate stamp of approval. "I'm so happy that Lindsay has found true happiness," he dished. "It's written all over both of them."
