That's exactly what I started doing, and why I sometimes stop writing for weeks, even months. After years spent writing every day, I sometimes feel like I just can't keep on writing about things that are worth it, so I just stop for a while, and do other things I enjoy.

I think it's a good piece of advice for everyone working on any creative field.

I guess self doubt never goes away, for anyone. We just have to learn how to ignore it and do what we need to do, even if we feel uncomfortable.
