Olivia Munn is afraid of setting herself goals.

The 34-year-old beauty, who recently starred in 'Mortdecai', has revealed that the fear of not realising her own ambitions causes her to avoid the risk of setting goals.

She said: ''I don't always do a lot of goal setting, only because I'm afraid, 'What if I don't make them?' It's easier if you kind of know what your goals are instead of just completely setting them out there.

''It's too hard to set career goals, especially in a career when a lot of the time it's not up to you - it's up to producers, directors, writers, the audience. If I don't make the goals, then I don't have to feel bad about not achieving them.''

Meanwhile, the actress also revealed she made her siblings re-enact 'Star Wars' with her when they were kids.

Olivia said the game proved her desire to be an actress from a young age.

She said: ''I grew up in a family of five siblings. I'm the second youngest. I loved making everyone laugh and impersonating teachers.

''If we all got into trouble at home and were sent to our rooms, I'd be the one to get everyone to laugh. I'd make everyone re-enact an entire movie. 'Let's all do 'Star Wars'!' I'd be Han Solo, but my brother would tell me I was Princess Leia. I just loved being able to play around. I always wanted to do be an actress, but of course you never think you're going to be able to.''
