When we do our very best it makes us feel good with the results and we find it unnecessary to compare ourselves to others. Some people are often comparing themselves to others and for many reasons , which we won't get into. Others are busy pointing out others flaws. Why? Well, for some reason it makes them feel better about themselves. Putting others down builds them up. What a sad thing!
If we ever find ourselves comparing ourselves to others we need to turn our focus to Jesus. Look at Jesus , not others. When you do that it will motivate you to do your best in all that you do.
"But let every man prove his own work, and then shall he have rejoicing in himself alone, and not in another." - Galatians 6:4
