As a full-time freelancer, I still need more work. However, some papers are impossible to fix, because the English is sooooooo bad. Ok, I can fix the grammar, but I cannot fix the meaning of some sentences. I have no idea what the hell the authors (or the translators) are trying to say!

I know time is money, at least for freelancers. When I cannot afford the time to play the guessing game, I surrender. (I just wrote to the client that I could not edit the paper.)

Do I feel like a loser now? Not really. Because I have never failed to edit any paper before, no matter how bad. This paper is just too much for me to handle.
