"I can’t" sounds like a verdict. "I can’t yet" leaves the door open. 

That small word does not promise effortless progress. It asks you to let your current ability be a starting point, rather than a permanent identity. 

You can acknowledge the gap without becoming the gap. Give yourself permission to be a beginner, then decide how you will learn.

"Becoming is better than being. The fixed mindset does not allow people the luxury of becoming. They have to already be." - Carol Dweck
