The effects of laziness are terrible.
“(…) however wretched he was, he did not want to change his position. . . . A heavy nightmarish lethargy gradually gained possession of him and fettered his limbs.”
Typhus by Anton Chekhov
The concept of laziness is understood superficially, however. The human condition overwhelmed by lethargy and laziness is more complex. There are many reasons of this indisposition: lack of believing in yourself, misunderstanding about your importance in life, the choice of the unfathomable objectives; and ultimately: anxiety, dejection and depression.
