Annan was always extremely harsh on himself.
He could sleep on command and never lingered in bed upon waking. He didn't smoke or drink, believing that he should never eat a bite more than needed once full. He maintained a balanced nutrient intake daily; he believed playing with his phone before sleeping was bad, so once in bed, he would not open his phone at all. He stopped eating three hours before bed and wouldn't start up a game either.
After all, he wasn't the product manager next door; no matter how serious his work, he wouldn't suddenly die from it.
Because he never slacked off during work hours, he was able to finish all tasks before leaving and didn't need to work overtime late into the night. This was a good habit he had formed since his student days.
And Annan never took on any extra tasks beyond his capability—all the workload he undertook was just the right amount, which he could complete with full effort.
