Impossible goal

The impossible goal I set for myself for this year was to learn to dance. I committed to practicing minimum of 30 minutes a day, 5x/week. I have been sticking with that. The issue I am having is that I am having a lot of feelings of discouragement. I want to be farther along than I am. I want my dancing to look like the instructor in the video’s dancing (it doesn’t). I try to just let myself feel discouraged, allow the emotion. However I think it is leading to some unwanted behaviors like avoiding practicing, or buffering with food as a way to feel better.

My model:
C: Learning to dance
T: I want to be better at this than I am. This is taking so long. I’ll never get there.
F: Discouraged
A: Half-hearted attempts, maybe quit early, buffer with food or social media
R: I don’t accomplish my goal.

Can you help me think of some alternative thoughts that spur me on towards my goal?
