Hope and optimism have defined my political career, and I continue to be hopeful and optimistic about Canada. Young people have been a great source of inspiration for me.

Don't let them tell you it can't be done.

Ideas are always more important than money.

My friends, love is better than anger. Hope is better than fear. Optimism is better than despair. So let us be loving, hopeful and optimistic. And we'll change the world.

Politics matters. Ideas matter. Democracy matters, because all of us need to be able to make a difference.

Treatments and therapies have never been better in the face of this disease. You have every reason to be optimistic, determined, and focused on the future. My only other advice is to cherish every moment with those you love at every stage of your journey, as I have done this summer.
