I try to make each to-do a single action statement. I find it helpful to have exactly what I need to do right in front of me. It also makes each item easy to check off, which makes it more likely I’ll do it.
Some to-do lists and apps let you list multiple steps but only reveal one step at a time which I also find helpful.
I write a pretty big list, but I try to hit three minimum. Anything I don't finish rolls over. It's a bit more realistic, so I can track what I haven't done in a way that's reasonable for the amount of free time I have.
