Lu Ping'an had always been somewhat complacent.
He was a patient waiting to die, who could suddenly pass away at any moment. Could he really be expected to strive hard, for his own offspring... well, it seems like he has no offspring, so there is really no reason for him to struggle.
If he had a goal at all, it was initially to make his parents' lives better... which is not difficult for the current Lu Ping'an.
Lu Ping'an knew that an astronomical amount of inheritance would most likely be a catastrophe for his old parents.
Therefore, as long as he was certain he had died, a considerable amount of consolation money would be periodically transferred into his parents' account. Moreover, there were entrusted professionals who would regularly take care of them and look after them...
He did not really have much to worry about... nor did he have many pursuits.
It wasn't that he wasn't diligent, but that he lacked the "motivation" and "habit" to work hard.
