this technique is an old Buddhist trick for tapping into the problem solving power of your brain. It is used to overcome the feeling of hopelessness that can immobilize a person when facing a difficult situation.
I like to use it to solve difficult problems that I encounter from day to day.
The idea is that when you are trying to decide what to do to solve a problem, you tell yourself to remember the solution. You might say to yourself "Remember! How did I solve this problem?"
This essentially tells your brain that there is a solution, and that the answer is somewhere in there. The brain responds to this assumption by searching for "the" solution. Our brains are always more powerful than we realize - we just need little "tricks" like this to get beyond our self-imposed limitations.
Try this technique several times a week in order for it to work more naturally.
