Don't compare your progress to others.
We all learn at different paces; we all make mistakes. Allow mistakes to be a learning tool, not a moment to criticize yourself. I have been looming for almost 3 years (started in 2011) and I am still learning. There are loomers more advanced than me but that's okay. I am learning and going at my pace, not theirs.
I enjoy just picking up a loom, no pattern on hand, and seeing what happens. It's one of the few "unknown" aspects in life I welcome. As I learn, I teach. As I teach, I learn. It is a cycle.
