The 28-year-old Ukrainian-born actress, who comes from a humble background, said she has a mediocre lifestyle which allows her to take up only those projects which she believes in.
"I actually live a very mediocre lifestyle. After doing [That '70s Show] for eight years and [Family Guy] for more than a decade, you are, financially speaking, in a very lucky position where you don't have to work for the sake of working.
"And I decided to take advantage of that. I don't live lavishly, so it's not like I have 20 assistants and travel privately and shop every day. I decided to step back and do things not just for the sake of doing them, but because I believe in them and I want to do them," said Kunis.
Kunis, who's enjoyed box office success with "Black Swan", "Friends With Benefits" and "Ted", admitted she's considered stepping away from acting in the next few years.
"This industry can eat you alive. I think it feeds you a lot of rubbish and then spits you right back out, and then you get caught up in it because so much of it is perception and opinion. The fact that there is no right or wrong is what I think is maddening," she said.
