Use your imagination to dream up worlds unseen. Use it to refurnish old items for new uses. Use it to create art that has no other purpose than to make people happy, or sad, or just to make them feel something.
But don’t worry.
Worry is a misuse of imagination.
Don’t worry about the future. Don’t worry about the present. And definately don’t worry about the past.
Sure, learn from the past, prepare for the future, and live in the moment – but once you’ve done these things all worrying does is make you see imaginary problems that come from imaginery situations that through worrying you deem imaginable.
I’ll say it again, worrying is nothing but the misuse of your imagination.
