In my work place we hired an intern who was pivoting careers and wanted to learn a new skill. The company was doing well, so we kept her on so long as she was trying. We patiently worked with her for years, but the skill NEVER clicked. She came from a robust background, so she was clearly capable, but we eventually figured out that she didn’t have the talent for it. She eventually decided that career wasn’t for her and left for another company - and in her new position she picked up on the different and required skill super quick. Our brains are elastic, sure, but they’re also hardwired in all different ways.
