I don't think this is necessary. If something is boring, you'll forget it. If something is interesting, you'll remember it. You'll think about it a few times, and perhaps discuss it with other people. You'll link it mentally to other parts of your worldview. All these things will increase your ability to recall it when necessary, without effort.

To improve memory generally, stay fit and live a sober and useful life.
