The flame-haired beauty recently took home the Best Actress Golden Globe for her role as CIA agent Maya in Kathryn Bigelow's political thriller 'Zero Dark Thirty' and with other potential awards in the pipeline - including an Oscar - she feels "anything" is possible after receiving so much support from family, friends and fans.
She explained: "I don't work for awards but when you receive support and encouragement, it opens me up more, it helps me be vulnerable.
"I think that's why I got so emotional at the Golden Globes - to feel the support I was getting at that moment made me feel like I could do anything."
Since soaring to fame after playing ditzy housewife Celia Foote in 2011's 'The Help' - which she won numerous Best Supporting Actress awards for - Jessica ensures she focuses more on her career and avoids causing any drama in her personal life.
She said: "I really made an effort to not put myself in situations where my private life becomes more interesting than my work.
"Like being seen dancing on a table in a nightclub. I'm not interested in that kind of, er, acknowledgement."
After a busy year of promoting and filming several different movies, Jessica, 35, plans to take a well deserved holiday to Europe in March.
She added in an interview with the Metro newspaper: "I'm going to go to Italy. Mostly, I'm going to spend time in Milan and hang out and eat a lot of pasta.
"I love the cinema in Europe, I love the museums. I would be so happy if I spoke three languages."
