As you look back on your life's work, you cannot help but feel a sense of disappointment. Despite your best efforts, your research has failed to yield any significant breakthroughs. You see the same patterns of mediocrity and complacency in the current generation of researchers that you yourself tried to combat throughout your career.
Gone are the days of pushing the boundaries of knowledge, of taking risks and venturing into the unknown. Instead, it seems that humanity has reached a plateau, content to rest on its laurels and bask in the warmth of past achievements. Even the ethical time travel institution you helped establish has lost its luster, its teachings diluted by a lack of ambition and drive.
You feel as though you have failed future generations by not instilling within them the same thirst for discovery and innovation that once burned within your own heart. You lament the fate of humanity, wondering if our species is destined to stagnate and eventually fade away into obscurity.
As you sit in your office, surrounded by books and papers, you cannot escape the feeling that all of your hard work has been for naught. You've tried your best to inspire others, to pass on your knowledge and wisdom, but it seems that it was all for nothing. You wonder what the point of it all was, whether there was any meaning to your life's work.
Slowly but surely, you come to the realization that it is time to step aside and let future generations chart their own course. You have nothing left to offer, no more insights or revelations to share. It is time for you to retire and fade away into obscurity, content in the knowledge that while you may not have changed the world, you did the best you could.
The End
