When you do something good for another person it is normal to feel good about that. But what's the true motive behind that help? Is it to help them or to gain brownie points for yourself? What you do for others should be done out of love and not to please them with the motive of winning their approval.
Before you agree to help someone ask yourself these 3 questions so your motives are in the right place and you're not doing it to be a people pleaser.
