Life's idea of fairness is that if you have more skill and ability then you get bigger challenges. That's usually the bosses idea of fairness as well. If we looked at higher expectations as being a compliment instead of being upset over someone else not having the same expectations, we would probably all be happier.
The Rolling Stones almost had it right.
"You can't always get what you want. But if you try sometimes, you just might find, you get what you need."
I would say that if you are focused, and you try all the time, you just might find, you get what you want as well.
