You're doing great!
As much as I wanted to move on to level 2, I don't think I was mentally prepared until day 8 or 9 of level 1. For me, it was all mental. Honestly, level 2 is tougher, but completing level 1 is a solid foundation since many of the new moves are built on the strength you've already acquired. You can do this!
I also knew I was ready to move to level 2 when I found myself, several times a day, humming the music in the 3rd circuit!
