It's hard to live a life without a few regrets, because we often make mistakes in our younger years and don't realise it until it's too late. If you could send a message back to your younger self, what advice would it contain?
The folks over at The Buried Life, a tumblr about getting the most out of life, posted a list of 20 things they should have known at 20 years old. For example, make older friends so you learn from them, stay in shape when you're younger so it's easier when you're older, do crazy things when you're young because you'll be too conservative to do them when you're not, and sleep. Not every item on their list will apply to everybody, but there are certainly a few good tips to keep in mind even if you're a little older than 20. What do you wish you knew when you were younger?
