What I look for in my own editing vs someone else's is majorly different. After my first draft I will really kind of rewrite my fics quite a bit. I find I put on about 20% WC wise in the editing process? One of the things I have found really helpful is that when I am doing it I actually use track changes in my own work, which sounds silly, but gives me a mental distance that is helpful. It can be annoying to have to then go back through and accept the changes, but it only really gets annoying on very long fics (Erised I see you). It's also helpful if I am not sure about a change I am making.

I've actually come to really love the self-edit process which surprises me. Still put it off every time though hahaha
