"Write what you know" can be a fantastic advice at times. But also be limited. Fantastic literature has been written both by people writing what they know and have personal experience of, and fantastic literature have been written by people dong the opposite though history. Elif Shafak fantastic talks on TED the subject make an argument of the point of not being limited to write what you know. In her case again and again running into the expectation that she should write about Muslim women and Muslim women issues.And the danger of be expected to write just what you know. That the nice advice "write what you know" can become a border, rather then making literature a bridge between people. I find this dilemma, this two edge knife interesting, since we all seen the examples when people writing not what they know become stupid and bar literature as best, or creating prejudice or distance between people at worst. How do you deal with the balance of writing what you know, and writing whatever you feel like writing?
