In other words, create your own version of a Sky Planter :

When you change your focus
from "How to find a job?"
to "How to make it easy for a job to find me?"
or
from "How to use social networking"
to "How to network our various social groups?"
or even
from "How to build a better Swiss army knife?"
to "What could a Swiss army knife be used to build?"

you create a shift that creates new ideas.
So when you get stuck:
- List as many questions as you can about your issue.
- Twist these questions.
- And answer your twisted questions until the ideas start flowing again.
