What is your biggest regret?

Not getting into IIT...i know i had the potential to get into a good one...pissed off the crucial time into watching movies,youtube,porn etc...it was sort of a dream(very big deal) for me to get into IIT...biggest fucking regret

I had been overthinking about the things which doesn't even matters for my betterment,life and future.

Not giving my family and friends time. insanely chased career. Left a hole in me that I guess will never be filled - I can try catching up but am sure it won’t be ever enough.

Not mining crypto when I was in college.
