Health is the soul that animates all the enjoyments of life, which fade and are tasteless without it.

The math is dead simple: it seems that the frequency of planets able to support life is roughly one percent. In other words, a billion or more such worlds exist in our galaxy alone. That's a lot of acreage, and it takes industrial-strength credulity to believe it's all bleakly barren.

Any passion to collect has some meaning behind it.

Seek not, my soul, the life of the immortals; but enjoy to the full the resources that are within thy reach.

The challenge of life, I have found, is to build a resume that doesn't simply tell a story about what you want to be, but it's a story about who you want to be.
