Honestly, I use Things 3 pretty much like the author uses his text-app. One single list for all to-do's. The beauty of Things 3 is that there is no feature bloat and unnecessary complexity like most to-do managers.

The important difference is automatic recurring tasks, and daily task will show up outside the app as that red bubble on its icon indicating how many things "need" to be done today, the rest is optional.

Crucially, you need to commit to it, and use it everyday - even if just a little. The authors notepad works because it's a daily simple thing, like you said.
