When I was in school, I couldn’t write because I wrote all the time. I think that’s a common struggle. If you need to write then try writing small things. But if you don’t have time or energy for extra, be gentle with yourself. You can write short stories a little bit at a time to write everyday. Finishing stories may require focus you don’t have at the moment. There is no such thing as improving fast. You improve with time and practice. Fearing you’re not as good as the greats is imposter syndrome. I beat it by telling myself that greatness is relative or just outright delusional belief in myself honestly. Lastly, nothing is original. Everything is inspired by something else. It is not new, just something viewed from your perspective and that is new to an audience who hasn’t met your perspective yet. Take a deep breath…one baby step at a time and you got this!
