Here are some quotes from
The True Warrior Athlete

The warrior spirit
is available to all
who seek it,
to the dedicated athlete,
the recreational athlete,
and to the non-athlete.
It is a way of life, an attitude,
a preparedness.

In and of itself
of what use is your sport,
to run faster or jump higher
or to hit harder?
To be truly meritorious
it must come to add
to your stature
as a human being.

Ultimately the goal
of the true warrior athlete
should be wisdom.
This is the highest level.
This is eternal.
Everything else is transient
and superficial in comparison.

When under stress say,
"Not only can I take this,
but I can take much more."
Thus you will thrive
under pressure
and not fold.
