"Fair" in my eye

No one is born to be identical.

So the game is started to be "unfair" in a sense. But what bring us to a fair game is the evenness of opportunity given. No matter you are bringing up a child, or a team member among your team, you have to ensure sufficient attendance is given to everyone.

It's pointless to blame the little one when they are not your rising stars. If they are all so mighty, this render the mentor to be worthless.

We already have exceeding amount of unfairness, and as a gentle being, keep giving out on what you can. You cannot change the world but your merit could makes "living" to be a better one.
