Education can sometimes not be individualized enough to the person.
You have to go at the right pace. You have to temper harder activities with ones that are easier.
You have to find a way to connect hard subjects to subjects that the learner enjoys and feels safe with.
Read a book about their favorite place: maybe it is the beach. Read a book about a Disney movie like Frozen, or try to identify key details, characters, etc, with a fun movie rather than something dry. Connect a math activity to the same types of things. Find what makes them light up and then show them how that connects to the harder activities.
You also have to be empathetic and never make someone feel chastised for trying, even if they have a hard time or it takes multiple tries. Sometimes that means you need more repetition, and sometimes it means you need to incorporate a new fun way, or maybe both.
You have to be constantly willing to find new materials and ways to engage the student so that they can go out of their comfort zone and start learning new things previously uncomfortable or unknown to them. Those aha moments are moments that are winning for both the student and the instructor every time.
