Greta Gerwig discussed the importance of learning on the job when it comes to filmmaking. in a recent conversation at the ?Director?s Chair? panel at the third annual Women in Entertainment Summit in Los Angeles, she said she?s noticed among her peers the tendency ?to over-prepare,? a sense that ?you need to be so qualified to do something, particularly for women." But after she wrote ?Lady Bird,? she felt she was ready to make her directorial debut even though she wasn?t yet an expert. ?The only way to get the knowledge is to jump and say ?I don?t know, can you help me?'? ?Why would you know what it is until someone explains it to you?? she asked. ?Finding people you can admit you don?t know things to is a big part of [learning and success].? she added.
