Sometimes, we need to work very hard. And if one doesn't when one should, then one cannot have what others can.
I used to work 14 hours daily in my early 30s in the MNC doing 2 people’s jobs because my hiring manager kana ambulance (worked 16 hours daily). In the end, the MNC relocated to the cheaper country.
Till today, I don’t see that we need to earn so much money to slog a working life worse than a slave.
