Ask HN: Solo developer, what's your recipe to start working?

Hello HN, I am a new solo developer who quitted job 19 weeks ago.

At this moment of my writing, I just don't want to work. I come across this problem a lot recently.

I don't have the urge to work, and it feels too difficult to focus.

I know that once I start, I will be productive. But I don't have a recipe to start. If my mood changes, I work. If not, I dont' know what to do.

I recently read that no matter what, you just work. I tried and failed to just work.

Any advice?
