(OK. That photo is nearly ten years old. I confess—my hair is grayer and there's less of it.)

I still feel like quoting Emerson:

[T]he best read naturalist who lends an entire and devout attention to truth, will see that there remains much to learn about his [or her] relation to the world, and that it is not to be learned by any addition or subtraction or other comparison of known qualities, but arrived at by untaught sallies of the spirit, by continued self-recovery, and by entire humility.  He [or she] will perceive that there are far more excellent qualities in the student than preciseness and infallibility; that a guess is often more fruitful than an indisputable affirmation, and that a dream may let us deeper into the secret of nature than a hundred concerted experiments.
