Jennifer Lawrence's New Year's resolution is to stand up for herself.The 'Silver Linings Playbook' star thinks she is a pushover and wants to learn how to be more assertive without upsetting other people. She told Marie Claire South Africa's January 2013 issue: ''My New Year's Resolution is to stand up for myself. It's hard for me. Nobody wants to be disliked. You always want to be polite and be nice. I tried to find a balance in saying what I mean and still being nice. I can't do it. I have this 'okay' attitude and everything. I end up allowing myself to get walked over and resenting it.'' Jennifer, 22 - who is dating British actor Nicholas Hoult - also revealed she prefers staying at home rather than having wild nights out. She said: ''I don't like going out that much. I'm kind of an old lady. After it's 11pm, I'm like 'Don't these kids ever get tired?' When I'm out, I think about my couch.'' While the stunning star has been blasted for her curvy figure, Jennifer has no plans to lose weight. She added: ''I'd rather look chubby on screen and like a person in real life.''
