Miranda Kerr tries not to take life too seriously.

The 31-year-old actress - who has four-year-old son Flynn with her estranged husband Orlando Bloom - tries to grab life by both hands and embrace all of the ups and downs that come her way because she believes every bumpy milestone is just part of evolution.

She explained: ''If I could say something to my younger self it would be, 'It's all part of an evolution. It doesn't matter whether it's positive or negative, it's an evolution. Understand what the end goal is, knowing that every day you're one step closer to getting there.' ''Life is about enjoying yourself and trying to make the most of moments. It's nothing to get too serious about.

''Even though I am a mother and I have a business to run, I feel like sometimes you can get too serious. Then it loses the fun and you have to wonder, 'Well, what am I doing this all for.' ''

The blonde beauty - who resides in Los Angeles - believes her positive outlook on life is down to her Australian mother Therese Kerr, who taught her to work hard and have a strategic business mind.

She explained to Australia's InStyle magazine: ''I've worked really hard to get where I am and that was instilled in me from a young age. And I've learned so much about life.''
