Conscious Mind, Subconscious Mind - Employer and Employee

If something in a machine breaks down, most often, the whole system is affected. If an accountant starts to do the lawyers work and the lawyer starts to do the accountant's work, most probably the results will be poor or unacceptable. And that's what happens with most people: we try to work out our problems, using our conscious mind instead of our subconscious. We think and think and think some more and analyze it deeply and struggle to come up with solutions for something. It makes our heads hurt, it stresses us out, it is frustrating and somehow we can't come up with any solution or sometimes when we do find a solution, we fail when trying to implement it. What the f*ck?
