Impossible thinking

In working on a difficult teaching issue, I got to thinking how the impossible can become possible. If I am faced with an impossible task. Rather than give up I could discuss it with someone Рwho should I approach for help?  What factor will make a difference? The impossible becomes feasible. I will then put the job into `background thinking` for a few days. Bit by bit I will finish it. It is also important to start the whole process in good time to allow for background thinking.

How do you approach ‘impossible tasks’?
