Nice. Mine's not so impressive, but when I was green and in college, I was casually job shadowing an older friend for a day at a major tech company, and was asked to take a look at some code that had an issue.
I spotted the bug in 30 seconds.
It was then I realized that even at the top of our profession, everyone is still human beings with their own sets of strengths and weaknesses, and I have just as much potential as anyone else.
