Stuck in a rut

 What do you do when you're in a rut? 

I have read several books about it and have heard myriads of opinions on the subject, and it appears after all my research that there is no one answer. 

A couple of things have helped me in the past. These are in no particular order.

• Doing something you've never done before.
• Doing something that scares you.
• Doing things backward. 
• Mixing routines up.
• Taking a long drive in the country (or city if you live in the country).

These are a few of my suggestions; please share your comments!
