Isla Fisher is looking forward to "reinventing" herself in the wake of her divorce.

The Wedding Crashers actress divorced Sacha Baron Cohen after 14 years of marriage earlier this year and after taking a break from her career to focus on their three kids, she has "really enjoyed" getting back to work and being able to rediscover who she is and what she wants out of life.

She told The Australian's WISH magazine: "I've really enjoyed going back to work.

"It's so exciting to focus your energy back on something. It's not that I fell out of love with being ambitious or working, it's just that I was more in love with motherhood, and I still am.

"It's amazing to me that at this point in my life I've got this opportunity, in a positive way, to reinvent what the last act of my life is now from the ground up.

"The kind of person that I would want to be with, if I ever wanted to get into another relationship, the kind of work I want to do, and who I want to be around socially, spiritually and emotionally.

"I've got time to discover what inspires me creatively, so it's been an amazing and lucky thing.

"For most parents, we focus on our kids and it's so divine and magical and so absorbing, but now I have some time where the kids aren't with me, so I get some time to think about what the future might hold for me. Which is exciting and also scary. Everything is scary."

The 49-year-old actress has found the best way for her to get over her heartbreak over the end of her marriage is to "keep moving" and agree to anything that comes her way.

She said: "This is totally personal and I say this with the caveat as it worked for me, but the concept of processing stuff and taking your time, thinking about it again and again, you don't really feel better that way. I didn't. Instead, it's like if you're riding a bike and you stop pedalling, you're just going to fall over. For me, it's been about keeping motion going and keeping moving.

"If I was feeling sad at any point in my life, or just depressed and I just wanted to pull the covers over my head, I just started saying 'Yes' to everything. Whether it's a dinner that I don't really want to go to, whether it's some new school mums having a barbecue, volunteering at the local fete."

And being "community minded" has been particularly helpful.

She added: "Being of service and continuing to say yes has really helped, accepting any invitation. I also basically just said yes to any job I got offered. I just tried to keep really busy and I think it has helped through the course of my life to just keep it moving."
