Growing up, people always tell us that hindsight is 20-20. But it isn't until we have actually lived through high school and college and made some key decisions (consciously or unconsciously) that this cliché piece of advice starts to come into focus.

When we're making those life choices (whether they're big or small), we're often relying heavily on our emotions to decide on one path or the other. It's safe to say that leaving our head out of the equation doesn't always lead to the best results. Yet there's no way to know that truth in the moment. Instead, we have to make that wrong decision, then look back and learn from our mistakes.

That's what life is all about, after all: We fall down, pick ourselves back up and then learn how to avoid that same fall in the future.

So, with that in mind, we gathered people of all ages and asked them the all-important question: What advice would you give to your younger self?

Think about it. If someone had just invented a time machine, and you were the first person who got to use it to go back and give your younger self one piece of wisdom, what would it be?

Some people told us they would use this opportunity to tell their younger selves to let the small things go and get a jumpstart on pursuing their dreams. Others had much more specific advice, wishing they could have avoided a bum boyfriend or embraced an awkward part of their body more. Bottom line: Everyone we interviewed had no problem thinking of past wrongs they would want to right.

It's a fun question to think about, as long as we also remember that those mistakes we'd want to fix also contributed to who we are today. Watch as everyday people do just that.
