It’s challenging. Writing down the weekly and daily big three have immediately confronted me with how much I let the day decide what I do. I haven’t had a lot of weekly reviews where I’m recording 100% completion on weekly goals. So my annual goals are languishing (which they were before, anyway.) I thought I had some drive towards my goals before but this has made it pretty clear I really didn’t. I think that attention on that deficit is really helpful.
On the daily pages, I’m using the left side (time-blocking/calendar, big three tasks, other tasks with light bullet-journal-type columns), and daily ritual checklists more than I’m using the right (notes.) I’ve no plans to move away from digital notes for this.
Carrying it around has been no issue and it’s very nice to have on the desk. My favorite video was Michael Hyatt personally demonstrating how to wear in the spine and binding a bit so it lays flat; his career in book publishing is paying off here! 
I bought the subscription that will send me a different color every quarter and am looking forward to the variety. I don’t at all like that “Full Focus Planner” is visible on the front in gold, even if the type is high quality.
Support/community has been okay. The month overview is set up for the planner’s quarter to begin on the first (the rolling quarters are a lot more flexible.) Since I received the journal several days into October, I contacted support so I’d receive the second planner in 2.5 months instead of 3 so I can set it up for use beginning 1/1. They were accommodating. Their new Focus on This podcast does a phone call with a planner user in the last 10-15 minutes that I’ve found helpful and interesting (I skip straight to it.) I haven’t interacted with the official closed Facebook group for planner users. I really wish they’d set up a Discourse forum. Though maybe I’m glad they didn’t since I could see the group being full of weird hacks and complaining about limitations. I’m not trying to shoehorn in a complicated system or replace OF, Notes, etc., so I don’t want to be tempted by other people doing that.
Overall, it’s all about the forced attention annual/weekly/daily goals, on paper, the reviews, and the rituals and I think they’ve made something useful. I like it a lot.
