While physics and mathematics may tell us how the universe began, they are not much use in predicting human behaviour because there are far too many equations to solve. I'm no better than anyone else at understanding what makes people tick, particularly women.
Science is not only a disciple of reason but, also, one of romance and passion.
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.
You must be the change you wish to see in the world
Strength does not come from physical capacity. It comes from an indomitable will.

It appears to me that we are, first and foremost, looking for the experience of love.
Meaning doesn’t lie in things. Meaning lies in us.
