Galatians 6:3-5

For if any person thinks himself to be somebody [too important to condescend to shoulder another's load] when he is nobody [of superiority except in his own estimation], he deceives and deludes and cheats himself. But let every person carefully scrutinize and examine and test his own conduct and his own work. He can then have the personal satisfaction and joy of doing something commendable [in itself alone] without [resorting to] boastful comparison with his neighbor. For every person will have to bear (be equal to understanding and calmly receive) his own [little] load [of oppressive faults].
