A sanskrit verse says
"Those who work hard to acquire knowledge die,
Those who sit idle and remain ignorant too die,
Then what is the use of clattering the teeth."
(In ancient time initial knowledge was acquired by cramming.)
Robert Browning in his poem "Rabbi-Ben-Ezra"
"Not on the vulgar mass
Called 'work' must sentence pass
Things done,that took the eye and had the price
O'er which, from level stand,
The low world laid its hand,
Found straightway to its mind, could value in a trice.
You are trying to weigh diamonds on hay scale (Phelps). World is not going to judge you by toil but by your achievements.
When Buddha pronounced his four Noble Truth he had similar interpretation. “All is suffering” and “There is cause of suffering” are first two Noble Truth.
