That there is no ideal life. Disappointments sit around every corner, so enjoy the here and now.

Never ever think that things are going to turn out all right.

It is necessary, I believe, to accept this idea, not only for science, but also for other things; it is of great value to acknowledge ignorance.  It is a fact that when we make decisions in our life we don't necessarily know that we are making them correctly; we only think that we are doing the best we can – and that is what we should do.

So achievement, to me, is something that just comes with this attitude of doing your work the best you can in a passionate way. It’s not something that you have to expect. It’s something that’s a consequence of what you do, but it’s certainly important.

Deprivation of the ability to speak is more like an attack of impotence, or the amputation of part of the personality. To a great degree, in public and private, I “was” my voice. All the rituals and etiquette of conversation, from clearing the throat in preparation for the telling of an extremely long and taxing joke to (in younger days) trying to make my proposals more persuasive as I sank the tone by a strategic octave of shame, were innate and essential to me. I have never been able to sing, but I could once recite poetry and quote prose and was sometimes even asked to do so.

And even if my voice goes before I do, I shall continue to write polemics against religious delusions, at least until it’s hello darkness my old friend. In which case, why not cancer of the brain? As a terrified, half-aware imbecile, I might even scream for a priest at the close of business, though I hereby state while I am still lucid that the entity thus humiliating itself would not in fact be “me.” (Bear this in mind, in case of any later rumors or fabrications.)

I have more than once in my time woken up feeling like death. But nothing prepared me for the early morning last June when I came to consciousness feeling as if I were actually shackled to my own corpse. The whole cave of my chest and thorax seemed to have been hollowed out and then refilled with slow-drying cement. I could faintly hear myself breathe but could not manage to inflate my lungs. My heart was beating either much too much or much too little. Any movement, however slight, required forethought and planning.

Nobody wants to be told about the countless minor horrors and humiliations that become facts of “life” when your body turns from being a friend to being a foe: the boring switch from chronic constipation to its sudden dramatic opposite; the equally nasty double cross of feeling acute hunger while fearing even the scent of food; the absolute misery of gut-wringing nausea on an utterly empty stomach; or the pathetic discovery that hair loss extends to the disappearance of the follicles in your nostrils, and thus to the childish and irritating phenomenon of a permanently runny nose. Sorry, but you did ask … It’s no fun to appreciate to the full the truth of the materialist proposition that I don’t have a body, I am a body.

Myself, I love the imagery of struggle. I sometimes wish I were suffering in a good cause, or risking my life for the good of others, instead of just being a gravely endangered patient. Allow me to inform you, though, that when you sit in a room with a set of other finalists, and kindly people bring a huge transparent bag of poison and plug it into your arm, and you either read or don’t read a book while the venom sack gradually empties itself into your system, the image of the ardent soldier or revolutionary is the very last one that will occur to you. You feel swamped with passivity and impotence: dissolving in powerlessness like a sugar lump in water.

There is an even longer shot that I do propose to attempt even though its likely efficacy lies at the outer limits of probability. I am going to try to have my entire DNA “sequenced,” along with the genome of my tumor. ... So perhaps I will be able to contribute a little bit to enlarging the knowledge that will help future generations.
