I'm good at sleeping. Some people can be left awake for hours, not me. Most of the time I'm asleep within 10 minutes of putting my head down. When I can't sleep though, it’s extreme. I could lie there for hours without feeling even remotely tired...

The future. I'm kept awake when I'm thinking of things I still need to do, challenges I need to face, and things to improve myself. Sometimes this can turn into obsessive worrying, other times it can leave me too eager to sleep.
