“If you can’t sleep, then get up and do something instead of lying there worrying. It’s the worry that gets you, not the lack of sleep.”
There is almost nothing worse than waking up in the middle of the night with your mind racing and not being able to shut it down. Well, that’s not true. Lying there, worrying about something is much, much worse. I am guilty of this far too often, and only in recent years have I begun to manage this more effectively.
Worrying is a 100% negative investment. Every single bit of energy spent on apprehension and anxiety is negative energy expenditure. Choose to spend your finite life positively; do something, even if it is wrong. You can always do something different if it doesn’t work out.
