It's the largest visible component of the space shuttle at launch.
The external tank provides a half million gallons of fuel for the
space shuttle's three engines thereby powering the craft with eight
million pounds of thrust to roar beyond Earth's
into space. But then, a mere eight and a half minutes into the
flight only seventy miles above
the tank's life is over. Now empty, it's jettisoned to disintegrate
in the atmosphere and fall into the ocean. The external tank is the
only component of the space shuttle which isn't reused.
Space Shuttle jettisons External Tank
It's often the biggest things in my life which have gotten me far,
very far, which are then no longer sufficient in and of themselves
for bringing forth the next expression of my life. I'm speaking
about the ways I be rather than about my gifts or
about my talents or about my best skills. If I tell the truth about
them, the ways I be which were once worth something, may no longer
even be useful for bringing forth the next expression
of my life. No matter how valuable a way of being was, no matter
how useful an erstwhile expression of
was, no matter how good I once was at being a certain
way (that could mean yesterday - not necessarily the
distant past), once it's outlived its usefulness, it's
simply dead weight. Unlike the space shuttle's external tank
which is automatically jettisoned, that to which I've become
inured, that to which I've become attached, the ways of being I've
come to rely on, those which I've incorporated into my repertoire
of strong suits are much harder to let go of even when
they've become dead weight just as suddenly as the external tank
after eight and a half minutes of flight, even when they too have
totally outlived their usefulness.
With some of my gifts, with some of my talents, with some of my
for example) I'm certain about where things are going and about
what has to be done to get them there. I know what the yet to be
will look like. I know what the final effect will be like. So I
simply do what I need to do to realize the result. In other words I
map out, step by step, what needs to be done. Then I complete each
step. And voila! The result is realized. Predictably.
Exactly as expected. No mystery here.
