Hi, I just needed to write this here.
Sometimes, my advisor does not have the time to read the chapters I write, or she is too lazy to do it. When that happens, she does not tell me she did not read it, but she just tell me that the writing, organization, and stuff like that are so awful that I have practically to rewrite everything from scratch.
At the beginning, when I thought she was being objective and trying to improve my work, I just felt sorry for myself or motivated to improve my writing. Eventually, I realized that when she was like that she had no idea of what she was talking about, but she had the need of telling me something, of giving me feed back.
Now, I just detest that. When she tells me things like that, I just want to tell her "but, of course, you didn't read it. You don't know what you're talking about", or just quit the PhD. :)
