If you meet someone for whom you feel a high degree of chemistry, rate how much chemistry on a 0 to 10 scale. If you rate the person a 9 or 10, then think twice about becoming involved with this person. Occasionally, such relationships work out, after a great deal of turmoil. But, more often, the strong chemistry you feel will be based on lifetraps that they trigger in you, rather than positive qualities that will make the relationship last.
