Actress Sienna Miller says she feels 'more grounded and complete' now.

The 33-year-old actress also mentioned that mistakes help in evolving as a person, reports mirror.co.uk.

`I feel more grounded and complete. Your 20s are the time for exploration and you kind of stumble and trip and pick yourself back up. All those experiences align to make you who you are.

`I think it's really important to have ups and downs and make mistakes - god knows I've made my fair share - but it all come together. I'm happy with me,` she said.

The `American Sniper` star delved upon her philosophy of life while talking to Australian Vogue.

`For a long time, the focus wasn't on my work, it was very much elsewhere. I was naive, I think. I was a young 21. Not totally green, I was by no means an innocent. But I had faith in the goodness of everyone and that led me into all sorts of situations that backfired,` she added.
