First you are immortal.
Your life ahead seems infinite. You’ll join the battle and vanquish the fools in your own time.
Then you are invincible. You revel mightily in your victories. Your small defeats are nothing but setbacks. Tomorrow is another day, and you plot to prevail.
Then you are practical. You take what you can get, and you’re cautious to hold what you’ve won. You dream of a better life. You mock the fools behind their backs and you take vacations to beautiful places.
Then you are dependable. You do what is needed, as often as necessary, and you do it promptly and under budget. You long to be free, but there are no more beautiful places.
Eventually, no more is asked of you, and everyone likes you, or pities you. You haven’t vanquished anything. Some of the fools have become your friends, and some of your friends have become fools. You don’t know what you’ve become.
Then again, finally, you are immortal.
