Trying To Get Foused Again

After two weeks of only riding bareback at the walk, with the occasional little trot, I saddled up today to attempt a schooling ride. My friend Joanne came to visit and she rode Savanah and I rode Rogo. Joanne did amazingly well with Savanah! She sits her trot beautifully and just looked so good on her - perfect position, had Savanah on the aids and using her hindquarters, etc. That was the successful side of the outing :) Rogo and I were atrocious! I'm not being hard on myself. We were really bad. We were far, far below being able to do even a Training Level 1 test. I'm sitting here smiling as I write this, because I'm not worried about it and in fact am so happy that I got him saddled and attempted a ride. A few days ago it just seemed like too much work, and I'm never like that (normally I have to ration myself). I know we'll get back to where we were. We had fun with a friend and ended with a ride on the beach, so what's not to love? Here's a picture of Joanne and Savanah that I took with my phone through Rogo's ears:

Joanne does a lot for dressage in our Province. Last year she organized a Stephan Peters clinic. Can you believe it? Stephan Peters here in Nova Scotia coaching local dressage riders? This year she's organized an Ingrid Klimke clinic. People are coming from as far away as BC. She created and maintains a Nova Scotia Dressage website that's an amazing resource. She's also training a young horse, a Hannoverian / draft cross and her daughter, a great young dressage rider, rides their other dressage horse at second level.
Backing up a bit, the two weeks of bareback were interesting and I learned from them. I felt my center of gravity mentally and physically lowering to a 'sack of potatoes seat', if I can describe it like that :) - my seat draped, not tight. This is how I sit on Savanah, but have never achieved consistently with Rogo. It's bad muscle memory and started from nervousness when I backed him. So although our technical prowess was non existent today, I think the bareback time was good. I'm going to try to do it at least twice a week, and incorporate time without stirrups into every ride.
Here's what I'm thinking for getting our schooling back on track:

1. Mentally focus. Plan the warm up exercises and try to stick with it unless I encounter something that really needs to be addressed. Today my mind wasn't with it yet.
2. Go large and get him forward before starting circles on days when he lacks impulsion. 
3. Do lateral work earlier in the warm up to get him more forward (this seems to work well for him, but I didn't do it today).
4. Do lots of transitions.

Also a lesson learned - I get easily distracted by having someone else in the ring. I'm so used to riding alone that through no fault what so over of the rider I'm in with, I get distracted and lose focus on what I'm doing. This is especially true for me in the warm up ring at shows, so riding with someone else is VERY good for me.
Any suggestions for how you get back on track when you've been off for a bit? Does it come right back to you, or do you have to work at it?
