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 of human beings.
We do not wish to see children precocious,
making great strides in their early years like sprouts,
producing a soft and perishable timber,
but better if they expand slowly at first,
as if contending with difficulties,
and so are solidified and perfected.
Such trees continue to expand with nearly equal rapidity
to extreme old age.
