I love paper too! However, I knew I was going to have a team and I knew I needed to be able to access things on multiple devices. So, I use both!
ClickUp operates as my 2nd brain because it's my central hub for business, it's all in one space.
Then, at the beginning of your week, you can map out on paper what you're needing to work on in your planner or on a to do list. I still do this sometimes when I have a lot going on and I want to ensure I'm hitting those top priorities. Many of my clients still do this too.
So yes, you can use ClickUp alongside your handy paper!
