Same. I use Apple Notes. I have a few notes pinned (regular work, creative work, self-education, travel, chores). I write tasks. Break them up into small tasks with indents. Pick a task from the pool and execute. "Regular Work" tasks get priority. But if I'm not feeling it, I move to the other ones. Once I finish a task, I delete it/replace it with next steps. Nothing fancy. No formatting except for indentation. Been crushing it.

But I will add, there is no right way to do things in life in general. Experiment, and do what works for you.
