When we get to the next world and we look around, we will see that the people who are important are not the people who accomplished a lot with their lives. It will be the people who made the most of what Hashem gave us. The person who was given very little ability but made the most of it will be more valued then the person who was given tremendous talents and didn't use them.
The key to judging ourselves is to look at how we used our potential versus how much we were given. The person who uses 85 percent of limited capacity will be more valued then the person who uses 35 percent of major capacity even though in this world he seemed so great.
From A Shiur by Rabbi Shafier-The Shmuz
