Let your subconscious do the thinking

How to solve problems: let your subconscious do the thinking: "Although I'm not consciously thinking about it, it percolates away in my subconscious, and a solution often announces itself when I least expect it."

I do this all the time. Something else that I do to assist in the subconscious assisting in solving a problem is think of the problem as I go to sleep. I wait until I'm in that state where I am almost asleep and then start to think of it. You would be surprised how many times a solution comes to mind either just prior to sleep or during the night. Just make sure you write things down right away as most likely will not remember in the morning. Works great.
