How do I stop chasing ratings instead of helping people?

You get decent scores now, but you catch yourself steering for the rating instead of truly helping, and the fact that it bothers you is a good sign. It means your conscience still knows the difference between looking helpful and being helpful, even when the system rewards the first one. The rating is a shadow of the real thing. When you serve the shadow, you can win the score and still leave the person no better off, and some quiet part of you knows it. But here is the mercy: genuinely helping someone is, over time, the surest way to a good rating anyway. The two are not really enemies, unless you let the shadow lead. Next interaction, aim only at actually solving the person's problem and let the score fall where it will. Ask yourself if they left better off, not just satisfied. Do that consistently and the ratings tend to follow honestly. Serve the person, not the number, and you get to keep both the score and your self-respect.
