You would have to do things differently, but things are still possible.
I would rather live. your mind will still be there, yea, sure it wouldnt be nice have to rely on people to do things, but as your mind developes, to make up for what you physically can't do, your quality of life will also improove.
All the people talking about life not being worth living if you cant ride, have you ever thought that maybe there are more important things to life than a lump of metal which you ride around on?!
Yo start off with, you may well be dissapointed that you can't do alot of things which you would normally do. But you would learn to adjust, and be glad that you are alive, and can be with loved ones etc...
