My friend is taking her MA in Creative Writing now. This after already completing half a teaching masters program and through a series of things that also included some poor communication on the school's part, she essentially failed their program. Took a year before she found a new program, and now is working on her own novel for her program. Sometimes she and I sit there late at night and chat about the devil that is writer's block. Sometimes she writes fics as a break. Sometimes we talk about TV. Or fashion. I'll send her pretty dresses or fashion disasters. Every award show, she's my red carpet style buddy. We both love colorful makeup. Or life. Things other than what will pressure her.
Wanting to improve is great. But letting the pressure get to you from outside sources is definitely not going to help. Fanfic should be a respite to get things going.
What things do help you get unstuck. Possible to do more of those things? You've acknowledged perfectionism, which is such a killer of creativity. It's so paralyzing. *hugs* Do you have particular things you can turn to to reduce your anxiety and minimize comparisons?
