Each of you should test your own actions. Then you can take pride in yourself, without comparing yourself to somebody else
NIV
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.
AMP
But let every man prove his own work, and then shall he have rejoicing in himself alone, and not in another.
KJV
