With time I grow--
growing similar to a tree
layer upon layer
my trunk
becomes ever sturdy.

Mental stamina
is the deepest of layers
that can outmatch
any muscle that I could have ever built.

Muscles dwindle within days,
but the fortitude to continue on
will never stifle or faulter;
nor will it ever  need a rest day.

So people
there are aesthetics of beauty
that the mind can accomplish;
some feats never dreamed
by even the most physically ept.

When you find time for the gym
remember that time was at a loss
from when you could
have learned something new
anywhere else.
