We say "YOLO" as a reminder to try new experiences. But what if the experience isn't even worth trying?

It's best to learn from others' mistakes. Here, then, are terrible experiences that we'll never do again and neither should you!

Rent a car while visiting NYC. -u/undead_opossum

Assume that every co-worker is a friend .-u/chrwiakgjw462q1

Settling for a relationship knowing you are not really happy. Never. Again.-u/Selthix

I was a server for 5 years. It was fun most of the time but God Almighty, the worst customers could drive a person to murder.-u/Prossdog

Go to Times Square for New Year's Eve, looks great on TV, not great in person unless you pay to get in the walled-off area.-u/Newfounder8

Swim in the sea at night whilst drunk. Nearly drowned.-u/MrCasterSugar

Go to Disney World’s Magic Kingdom on Christmas Day. Shoulder-to-shoulder people, insane lines, and nothing special I couldn’t see earlier in the month.-u/mGreeneLantern

Now I always pee before cutting jalapeno peppers. The other way around, never again.-u/Jinzot

I refuse to ever do retail again, people are literally such a*****es and don’t realize your trying to help them and still get their job done-u/Sufficient_Back_3156

Childbirth and the postpartum period. Love my daughter to death. One and done.-u/Alarming-Quarter-396

Getting attached too quickly to someone that wanted me first. Getting played by someone like that is a different kind of pain. If you lost interest make it more obvious geez.-u/agaho

Pulling an all nighter. Age is catching up on me.-u/lividguitarist

Binge drink. I used to go on benders for a week or two. Now I barely ever drink-u/Jhellams83

3 1/2 hour jungle hike with almost no water and wearing only a bathing suit and water shoes.I didn't do this by choice but was more or less forced into it and it SUCKED.-u/KnockMeYourLobes

Stay at a job I’m unhappy at-u/Apprehensive_Let_843

Camping by a river that was flooded by melting snow from an area that was 6 hours away and having to be heli-rescued. It was super embarrassing.-u/BonfireFanatic

Bungee jump.. as soon as my feet left the edge all I could think was "well that was stupid"...It was exciting and probably safe enough.. but it was enough for me to know I will never willingly do that again.-u/halversonjw

Working in academia - left two years ago and never looking back. -u/STATEofMOJO

Smoke. Did it for 14 years. I feel so much better having quit. Been about 10 years since and the amount of money saved and the smell and the cough-u/Memorydump1105

Work at McDonald's.Never again. .... Never again.-u/wolfeyes555

Speed (amphetamine). The high doesn’t feel like a high but everyone around you can see that you are out of your mind. And the comedown was the only time where I truly wanted to die. Absolutely horrible. For reference I’ve taken lots of other drugs and experienced different comedowns, nothing compared to that.-u/T8_Thpinal

Swim with dolphins. They’re fast, large animals and we don’t belong in open water.-u/dooogall

Any job involving tech support or customer service. I'll starve before I deal with entitled older people who demand the latest technology, but refuse to learn how to actually use their new technology and expect the world to bend over backward to satisfy their unrealistic demands. Half of them don't think plugging in their TV is a requirement before calling and screaming that "this darnedest, useless smart tv don't even want to come on and I've tried EVERYTHING! My old dumb TV lasted 40 years and never had a problem, now tell your boss Mr. Netflix to send me a new TV and give me a refund!"-u/djb2589

Food challenges. I tried eating a 1kg steak once and almost threw up. That was my first and last food challenge.-u/p15i

Birthing without an epidural. I had laughing gas instead. Made me high as a kite. I screamed in pain while I was dissociating into space.-u/tuxedo_cat_commander
