Stuck in the System

I haven't been riding lately due to some family issues. Also, both of my Parelli horses have been limping, go figure. I played a little online just asking for simply stuff, like backing by tail, sideways, etc. They were very obedient with this. Maurice's clinic is approaching fast and I feel like I'm in the exact same spot as 6 mos. ago. What's up with that? I worked so hard this summer trying to improve on what I learned in March. I'm feeling stuck!
