Then, try to spend a day (or an hour, or even ten minutes) without using this concept. Whenever you find yourself trying to pass through it to get from one thought to another, don't let yourself - find some way around instead. You probably won't be able to, but this the expected result; the point is to have the experience of trying. If you manage it easily, the concept you were trying it with wasn't actually very central.
Now try to find at least two concept clusters. Maybe you'll be able to find and access "happy"/"sad", or "business"/"pleasure", or "technical/artistic". Once you have some ability to move between the two of them deliberately, try replaying a recent event that was significant to you from the point of view of each, and see what differs.
