Pardon for interrupting in this convoy between you and the author but let me add something;
You wanted to indicate that we should remain satisfied with all the blessings we have, but do we have to struggle for more achievements??
If yes then the balance is needed because according to Charles Darwin "nature favours the fittest "
Secondly, if we keep on struggling to fill the emptiness will we be at the point where life would be overloaded, suppose we keep on filling our pockets with pearls and the time comes when overfilling will restrict us to take even a single pearl from this stock. What will we do, possibly we will empty the pocket Nah?? So do what is enough to fill the emptiness can engage you in trouble.
I wanted to respond to you more dude but the language you have written is a bit sophisticated for me, do edit the comment(a privilege not priledge ) ( we do struggle not we are struggle)
Just a constructive criticism dude don't mind it .
