Some are good with details, some can comprehend only the broad strokes of an idea. Some friends do better with other people in person, while others are better on the telephone. Some people have great difficulties with numbers, some with dance steps, some with verbs. Everyone is gifted with something, too. Some have nimble fingers, some have nimble minds.
Some people are simply wonderful with animals, some with tulips.
Workability works with a person's strngeths and gifts that make them valuable employees. It may seem a small point, but whehter you are color blind or lacking in upper body strength or inclined to forget names, to be human is to have limitations. Thinking about your own personal limitations with a compassionate heart will teach you a lot about relating to people with major, even highly visible, disabilities. As a group, a society, we define which disabilities are disqualifying, which accommodations are reasonable, which limitations, in others and ourselves, we can accept, live with, perhaps learn instead to celebrate the gifts.
