The problem you're running into isn't exactly what you might be thinking it is. You actually can learn the fight just as well as other people but it takes some tricks to get there. The first is to understand it's okay to make mistakes. The second is to block out the time you want to spend doing the activity so there's nothing else that is pressing. FYI this is not to eliminate distractions, but to help make sure that there's nothing else that is eating away at you inside.

"Oh, I got to go clean the kitchen, I'm behind schedule on it..." "I didn't finish that task I had yesterday, I got to try harder tomorrow", etc, are examples of thoughts that can eat away at you without realizing it, because it can turn into a self blame game where you punish yourself. If you forget to clean the kitchen, just do it tomorrow. You don't need to try harder to complete the task you didn't finish during the work day because the only one who is saying that is yourself, not your boss at work.

Kind of hoping that helps a bit.
