I might have been just as happy to have been a practicing primary-care doctor. But as a medical student, I had interacted with patients suffering from neurodegeneration or acute clinical schizophrenia. It left an indelible mark on my memory.

My four years in the Marine Corps left me with an indelible understanding of the value of leadership skills.

Even though chess isn't the toughest thing that computers will tackle for centuries, it stood as a handy symbol for human intelligence. No matter what human-like feat computers perform in the future, the Deep Blue match demands an indelible dot on all timelines of AI progress.

Watching indelible ink (what they use to denote you voted during elections in India) fade/peel off from your finger, albeit slowly, is fascinating. It is a gentle reminder that everything is, after all, impermanent. Nothing lasts forever!

Our moments of Inspirational are not lost though we have no particular poem to show for them; for those experiences have left an indelible impression, and we are ever and anon reminded of them.

Strip back the beliefs pasted on by governesses, schools, and states, you find indelible truths at one's core.

After that day, I discovered one indelible truth. I discovered that love wasn't everything that mattered in life. It was an emotion that not many had the luxury of feeling without any pain attached to it. Many say that love will set you free, but I disagree. Love is a cage, a very painful one; its gilded bars made with yearning, heartache, and unfulfilled dreams. And the moment I realized that love wasn't necessary to one's survival I became free. No one would have the power to hurt me again.

Losing a belief in free will has not made me fatalistic-in fact, it has increased my feelings of freedom. My hopes, fears, and neuroses seem less personal and indelible. There is no telling how much I might change in the future. Just as one wouldn't draw a lasting conclusion about oneself on the basis of a brief experience of indigestion, one needn't do so on the basis of how one has thought or behaved for vast stretches of time in the past. A creative change of inputs to the system-learning new skills, forming new relationships, adopting new habits of attention-may radically transform one's life.

You forget all of it anyway. First, you forget everything you learned-the dates of the Hay-Herran Treaty and Pythagorean Theorem. You especially forget everything you didn't really learn, but just memorized the night before. You forget the names of all but one or two of your teachers, and eventually you'll forget those, too. You forget your junior class schedule and where you used to sit and your best friend's home phone number and the lyrics to that song you must have played a million times. For me, it was something by Simon & Garfunkel. Who knows what it will be for you? And eventually, but slowly, oh so slowly, you forget your humiliations-even the ones that seemed indelible just fade away. You forget who was cool and who was not, who was pretty, smart, athletic, and not. Who went to a good college. Who threw the best parties Who could get you pot. You forget all of them. Even the ones you said you loved, and even the ones you actually did. They're the last to go. And then once you've forgotten enough, you love someone else.

Character is the indelible mark that determines the only true value of all people and all their work.

The shock of any trauma I think changes your life. It's more acute in the beginning and after a little time you settle back to what you were. However it leaves an indelible mark on your psyche.
