The key to immortality is first living a life worth remembering.

If you love life, don't waste time, for time is what life is made up of.

Life well spent is long.

Do not go where the path may lead; go instead where there is no path and leave a trail.

I think computer viruses should count as life. I think it says something about human nature that the only form of life we have created so far is purely destructive. We've created life in our own image.
