I have great empathy and understanding for others.

Empathy and understanding come apart more often than they are paired. You can feel somebody's distress accurately and have no idea what is causing it. You can grasp a situation in complete detail and feel nothing about it at all.

The first without the second produces well-meaning uselessness - sympathy delivered to the wrong address.

The second without the first produces advice that is correct and unbearable.

Having both is rarer than it sounds, and it mostly shows up as patience: staying in a conversation long enough to feel it and work it out, when either one alone would have let you leave earlier.
