My advice to other disabled people would be, concentrate on things your disability doesn't prevent you doing well, and don't regret the things it interferes with. Don't be disabled in spirit as well as physically.
The thought system that dominates our world is laced with selfish values, and relinquishing those values is a lot easier said than done. The journey to a pure heart can be highly disorientating. For years we may have worked for money, power and prestige. Now all of a sudden we've learned that those are just the values of a dying world.
