15 people share the most unintentionally profound thing they've ever heard.

We've all looked for signs in the stars, quotes that will change our lives, or wisdom that penetrates all the barriers of experience and difference.

Ironically, the most profound chunks of wisdom often slip out in ways we'd least expect. A passing exchange with someone can radically alter our entire life perspective. A simple sentence can cause us to reexamine and reflect on our own behaviors.

In a popular Ask Reddit thread, people shared the most unintentionally profound things they've ever heard, and it's fascinating.

1. From DPAW_:

I'm not here to go into debt to impress a neighbor I don't like. - Grandpa

2. From ocktick:

When I was in Italy visiting my 88-year-old grandpa last month he was showing me around his friend's old house. He picked some random rock up off the ground outside, a reasonably large-sized one with smooth edges and no cracks.

He said to me in his sort of broken English, 'rock must roll many times to get that round.' and then started laughing hysterically, like he had been saving that 'joke' for the last 40 years. I'm not even sure why I find it so profound, but I think about it a lot.

3. From D-PadRadio:

'Keep cool, never freeze.'

Read that on a can of juice concentrate.

4. From DBish95:

This summer I got a job as a mover to make some extra cash before university. I'm often paired up with some pretty sketchy drivers who can say some weird stuff. One day I was working with a guy and he said something that really inspired me.

He said:

'Be the guy who gives a f*ck, there's already to many who don't.'

This simple sentence that he thought nothing of is now part of my own personal life motto as weird as it sounds. In every interaction I always try to 'give a f*ck' and my life has honestly improved.

5. From Not_Paddy:

Was watching a soccer match when a younger player (can't remember who) was chasing after a ball that looked like it was going out of bounds.

The commentator kind of chuckled and said, 'Well there's no such thing as a lost cause when you're 18.'

I was 17 at the time and it really spoke to me.

6. From brownpixel:

A sign by a step in a Chinatown shop: 'BE CAREFULLY!'

7. From hdhdhdhdh:

From the man on the phone at the table next to me at Barnes & Noble: 'Most problems, you can recover from. Like, if someone breaks into your house, it's not the end of the world.'

'But the anxiety you can feel about the possibility of something like someone breaking into your house can ruin your life.'

8. From Kowabunga_Dude:

My friend joined a culinary school, in one of her books there is a section on knife safety. One of the rules started out, 'A falling knife has no handle...'

9. From p1zawL:

I was chillin in a park with some friends, and some couple on the sidewalk in front of us get in a huge argument and are yelling at each other. At one point the girl goes:

'You can't do nice things for me and then get pissed when I don't return the favor. I didn't ask you to do those things, you did them on your own. You shouldn't do nice things for people to get something back, then it's not nice, it's blackmail.'

'You should do nice things just to be nice.'

As soon as she said that, I realized I was guilty of doing just that. I've tried to not do that ever since, and it's a good thing to keep in mind when you think you are being nice. Are you really?

Or are you just trying to manipulate people into being in your debt?

10. From rip-pimpc:

'I feel OK about dying now, I've had a good life. I danced a lot.'

A dying patient of mine on the ambulance.

Edit: For everyone asking, yes she died a few days later in the hospital. She was very old with a long list of medical conditions so I'm sure she and her family knew it was coming for quite some time.

11. From flxtr:

For our honeymoon, my wife and I went to Savannah, GA. We took a tour of a cemetery and there was an old tombstone for a woman and it said 'She Done What She Could.' At the time we laughed about it and thought it was odd and shallow.

Fast forward 11 years and 2 kids later and it has become our mantra to remind ourselves that we give our best in raising our kids and living our lives and that hopefully, it all works out.

12. From narcolepticwalrus:

My friend said she felt bad when the woman at Chipotle came and took our stuff because she could have done it herself. The woman said 'There are so many things in the world to feel bad about. This is not one of them.'

13. From hlfempty69:

One time, me and a couple buddies were getting high in a parking lot across from a taco bell. There was an older homeless black man sitting on a bench out in front of the taco bell talking to a tree.

We started giggling and decided to go over and talk to him. We were just like 'dude, why are you talking to a tree? Haha...'. The old man looked up and then dropped his head and in a soft voice said, 'Man, everyone needs someone to talk to.'

Stopped us dead in our tracks and almost brought me to tears.

14. From b0op:

'You think you've had the best but that's only because you haven't allowed yourself to have better.' -My brother to me after my boyfriend and I broke up.

15. From supermanhat:

I once ordered a hot dog (in Chicago), and the man behind the counter asked me what I wanted on it. I said 'Everything.' In Chicago, 'everything' on a hot dog has a fairly specific meaning. The man looked down at the hot dog, then at me.

Then back at the hot dog. Then back at me. Finally, after a moment, he looked me square in the eye and, in almost reverent tones, he quietly said, 'Everything's not going to fit on a hot dog.'
