This is brilliant.
I live this through the closest person to me. He set high goals for himself and won't go about it any other route. He refuses to be happy until this is achieved. Even when I enlighten him the different ways he could quit delaying his happiness and as well obtain this academic achievement alongside each other easily since he has been offered to be rendered assistance, he still stays fixated on his way of going about it.

Truth is, many will never be content until it's either too late or they die. Hard to take in, but that's just how it is when we only see in one light.

Then again, maybe the movers and shakers' happiness is tied to discontent.
