Henry David Thoreau

"I am struck by the fact that the more slowly trees grow at first, the sounder they are at the core, and I think that the same is true for human beings. We do not wish to see children "precocious," like sprouts producing a soft and perishable timber, but rather, better, as if contending gradually with difficulties, they are solidified and gradually perfected."  - from the journal of Henry David Thoreau
