When you are trying to fall asleep, but your brain keeps making you think of something important, write it down in a notebook beside you and go back to sleep.

It clears your head, and then you don't have to worry about trying to remember it and you will have it for later. Also, I guarantee that most likely when you read it the following day, what you thought was so important will be stupid and irrelevant. <br><br>Edit: oh dear this must be a life pro tip as well as a dummy fail tip because oh boy this blew up. I guess this must be important for people who get these problems, who knew? I’m just honoured it’s staying at the top, and I appreciate all the awards. I really thought this one would be ignored within hours, but no. Worth the beer thank you!
