This is not me.
The other day, I tried an aerial dance class at a studio near my house. I've been doing things like this lately - signing up for classes (dance, pottery, crochet) just because they sound fun. Because I want to, and because sometimes the kids are with their dad, and so I can. It was only me and one other woman in the class, and the other student had been dancing for a year, so I was a little embarrassed at just how bad I was clearly going to be. The first time I tried to kick my legs up I failed - obviously - and felt all graceless and vaguely elephantine, but even as I flailed there on the ring with my limbs sticking out in every direction, the other student and the instructor were standing there cheering for me. Actually cheering.
You're doing SO GREAT! You've got this!
