That's totally it. I will have these clear ideas when I'm anywhere else and I'm hyping myself up for the moment when I get back in front of a screen and nothing happens when I actually do.

Thank you for the advice! I definitely have some stories that I'm in the middle of that could use some nudging.

but it never really helps to get something started when I'm not sure where to start.
Fair. I usually just have to force myself to start and then let it go from there. Beginnings and endings have never not been a struggle.
