90 + 10

The sum of 90 and 10 is 100. So is the sum of 10 and 90.

When someone gets a 90, we wish they had got the 10 also, so that they would get a total 100. But when someone gets a 10, we don't cheer them to get another 90 so their total becomes a 100.

The reason is simple. In the 1st case only 10 is needed to get the 100. In the latter case, 90 is needed to get a 100. We don't roundoff a 10 to a 100.

Often we think ourselves to be at 90 and that we need only 10 more to get a century. We don't realize that people rate us at only a 10.

It's very painful when we realize for the 1st time that we were at 10 throughout the time we thought ourselves to be 90.
