I wouldn't normally post song lyrics to HN, but this just seemed too appropriate:
*And I want it so much.
Close my eyes, I can taste the Mars dust in the air.
In the darkness the space stations shimmer in orbits that I will not share.
But I'll teach the student
Who'll manage the fact'ry
That tempers the steel that makes colonies strong.
And I'll write the program that runs the computer
That charts out the stars where our rockets belong.
It will never get easy to wake from my dream
When the future I dream of is so far away.
But I am willing to sacrifice
something I don't have For something I won't have
but somebody will someday.*
