It surely has importance to those who have been brought up (or should I say "were brainwashed") to believe it has.

This belief surely doesn't help those who suffer from the physical state you mention: they surely feel worse if they're led to believe their lives are worthless without it.

Motivation doesn't necessarily have to come from the conviction that our lives are parts of The Grand Scheme of Things, or The Big Plan or whatever. Life itself should be motivation enough - you got that one to yourself, use it to do something good with it. Definition of "good" here may vary, but in general your intuitive definition of "good" is probably the best definition.
