The more one feels imperfect in Krishna’s service, the more he is advancing in Krishna Consciousness. Even the topmost devotees feel they are inadequate in their service to the Lord. So it is good to feel inadequate, and to try harder to please Krishna with better service. But one should never feel, oh, I have seen Krishna, and so I am reached perfection — this is not Krishna Consciousness.
Please continue your very good service, and do not feel any feeling of uselessness. It is true that Krishna has given some the opportunity to serve Him by nice writing, some by good business ability, some by nice cooking, and so on, but these various services are all accepted equally by Krishna. On the transcendental plane, one service is as good as another. There is no question of higher or lower. We are very tiny, and so we cannot really do very much. Simply we can engage our time and energy, and that is all Krishna sees. He sees this boy or girl is spending his time in My Service, and He is pleased.
